Read the article(s) carefully and use the questions below to help you identify how and why the research was carried out. Look at the following sections: 

Introduction

• What was the objective of the study?
• What methods were used to accomplish this purpose (e.g., systematic recording of observations, analysis and evaluation of published research, assessment of theory, etc.)?
• What techniques were used and how was each technique performed?
• What kind of data can be obtained using each technique?
• How are such data interpreted?
• What kind of information is produced by using the technique?
• What objective evidence was obtained from the authors’ efforts (observations, measurements, etc.)?
• What were the results of the study? 
• How was each technique used to obtain each result?
• What statistical tests were used to evaluate the significance of the conclusions based on numeric or graphic data?
• How did each result contribute to answering the question or testing the hypothesis raised in the introduction?
• How were the results interpreted? How were they related to the original problem (authors’ view of evidence rather than objective findings)? 
• Were the authors able to answer the question (test the hypothesis) raised?
• Did the research provide new factual information, a new understanding of a phenomenon in the field, or a new research technique?
• How was the significance of the work described?
• Do the authors relate the findings of the study to literature in the field?
• Did the reported observations or interpretations support or refute observations or interpretations made by other researchers?

These questions were adapted from the following sources:  Kuyper, B.J. (1991). Bringing up scientists in the art of critiquing research. Bioscience 41(4), 248-250. Wood, J.M. (2003). Research Lab Guide. MICR*3260 Microbial Adaptation and Development Web Site . Retrieved July 31, 2006.

Once you are familiar with the article, you can establish the research context by asking the following questions:

• Who conducted the research? What were/are their interests?
• When and where was the research conducted?
• Why did the authors do this research?
• Was this research pertinent only within the authors’ geographic locale, or did it have broader (even global) relevance?
• Were many other laboratories pursuing related research when the reported work was done? If so, why?
• For experimental research, what funding sources met the costs of the research?
• On what prior observations was the research based? What was and was not known at the time?
• How important was the research question posed by the researchers?

These questions were adapted from the following sources: Kuyper, B.J. (1991). Bringing up scientists in the art of critiquing research. Bioscience 41(4), 248-250. Wood, J.M. (2003). Research Lab Guide. MICR*3260 Microbial Adaptation and Development Web Site . Retrieved July 31, 2006.

Remember that simply disagreeing with the material is not considered to be a critical assessment of the material.  For example, stating that the sample size is insufficient is not a critical assessment.  Describing why the sample size is insufficient for the claims being made in the study would be a critical assessment.

Use the questions below to help you evaluate the quality of the authors’ research:

• Does the title precisely state the subject of the paper?
• Read the statement of purpose in the abstract. Does it match the one in the introduction?

Acknowledgments

• Could the source of the research funding have influenced the research topic or conclusions?
• Check the sequence of statements in the introduction. Does all the information lead coherently to the purpose of the study?
• Review all methods in relation to the objective(s) of the study. Are the methods valid for studying the problem?
• Check the methods for essential information. Could the study be duplicated from the methods and information given?
• Check the methods for flaws. Is the sample selection adequate? Is the experimental design sound?
• Check the sequence of statements in the methods. Does all the information belong there? Is the sequence of methods clear and pertinent?
• Was there mention of ethics? Which research ethics board approved the study?
• Carefully examine the data presented in the tables and diagrams. Does the title or legend accurately describe the content? 
• Are column headings and labels accurate? 
• Are the data organized for ready comparison and interpretation? (A table should be self-explanatory, with a title that accurately and concisely describes content and column headings that accurately describe information in the cells.)
• Review the results as presented in the text while referring to the data in the tables and diagrams. Does the text complement, and not simply repeat data? Are there discrepancies between the results in the text and those in the tables?
• Check all calculations and presentation of data.
• Review the results in light of the stated objectives. Does the study reveal what the researchers intended?
• Does the discussion clearly address the objectives and hypotheses?
• Check the interpretation against the results. Does the discussion merely repeat the results? 
• Does the interpretation arise logically from the data or is it too far-fetched? 
• Have the faults, flaws, or shortcomings of the research been addressed?
• Is the interpretation supported by other research cited in the study?
• Does the study consider key studies in the field?
• What is the significance of the research? Do the authors mention wider implications of the findings?
• Is there a section on recommendations for future research? Are there other research possibilities or directions suggested? 

Consider the article as a whole

• Reread the abstract. Does it accurately summarize the article?
• Check the structure of the article (first headings and then paragraphing). Is all the material organized under the appropriate headings? Are sections divided logically into subsections or paragraphs?
• Are stylistic concerns, logic, clarity, and economy of expression addressed?

These questions were adapted from the following sources:  Kuyper, B.J. (1991). Bringing up scientists in the art of critiquing research. Bioscience 41(4), 248-250. Wood, J.M. (2003). Research Lab Guide. MICR*3260 Microbial Adaptation and Development Web Site. Retrieved July 31, 2006.

After you have evaluated the research, consider whether the research has been successful. Has it led to new questions being asked, or new ways of using existing knowledge? Are other researchers citing this paper?

You should consider the following questions:

• How did other researchers view the significance of the research reported by your authors?
• Did the research reported in your article result in the formulation of new questions or hypotheses (by the authors or by other researchers)?
• Have other researchers subsequently supported or refuted the observations or interpretations of these authors?
• Did the research make a significant contribution to human knowledge?
• Did the research produce any practical applications?
• What are the social, political, technological, medical implications of this research?
• How do you evaluate the significance of the research?

To answer these questions, look at review articles to find out how reviewers view this piece of research. Look at research articles and databases like Web of Science to see how other people have used this work. What range of journals have cited this article?

These questions were adapted from the following sources:

While writing a research paper can be tough, it can be even tougher to evaluate the strength of one. Whether you’re giving feedback to a fellow student or learning how to grade, you can judge a paper’s content and formatting to determine its excellence. By looking at the key attributes of successful research papers in the humanities and sciences, you can evaluate a given work work against high standards.

Examining a Humanities Research Paper

• A strong thesis statement might be: “Single-sex education helps girls develop more self-confidence than co-education. Using scholarly research, I will illustrate how young girls develop greater self-confidence in single-sex schools, why their self-confidence becomes more developed in this setting, and what this means for the future of education in America.”
• A poor thesis statement might be: “Single-sex education is a schooling choice that separates the sexes.” This is a description of single-sex education rather than an opinion that can be supported with research.

• In the example outlined above, one could theoretically create a valid argument for single-sex education negatively impacting the self-esteem of girls. This depth makes the topic worthy of examination.

• Ask yourself if the thesis feels obvious. If it does, it is probably not a strong choice.

• The paragraphs should each start with a topic sentence so you feel introduced to the research at hand.
• A typical 5-paragraph essay will have 3 supporting points of 1 paragraph each. Most good research papers are longer than 5 paragraphs, though, and may have multiple paragraphs about just one point of many that support the thesis.
• The more points and correlating research that support the thesis statement, the better.

• A paper with little supporting research to bolster its points likely falls short of adequately illustrating its thesis.
• Quotations longer than 4 lines should be set off in block format for readability.

• For example, if a thesis statement were that cats are smarter than dogs. A good supporting point might be that cats are better hunters than dogs. The author could introduce a source well in support of this by saying, “In animal expert Linda Smith’s book Cats are King , Smith describes cats’ superior hunting abilities. On page 8 she says, ‘Cats are the most developed hunters in the civilized world.’ Because hunting requires incredible mental focus and skill, this statement supports my view that cats are smarter than dogs.”
• Any quotations that are used to summarize a text are likely not pulling their weight in the research paper. All quotations should serve as direct supports.

• Doing this is a mark of a strong research paper and helps convince the reader that the author’s thesis is good and valid.

• A good research paper shows that the thesis is important beyond just the narrow context of its question.

Evaluating a Sciences Research Paper

• An effective abstract should also include a brief interpretation of those results, which will be explored further later.
• The author should note any overall trends or major revelations discovered in their research.

• The author of a successful scientific research paper should note any boundaries that limit their research.
• For example: If the author conducted a study of pregnant women, but only women over 35 responded to a call for participants, the author should mention it. An element like this could affect the conclusions the author draws from their research.

• An effective methodology section should be written in the past tense, as the author has already decided and executed their research.

• A good results section shouldn’t include raw data from the research; it should explain the findings of the research.

• A strong discussion section could present new solutions to the original problem or suggest further areas of study given the results.
• A good discussion moves beyond interpreting findings and offers some subjective analysis.

• The author might think about the potential real-world consequences of ignoring the research results, for example.

Checking the Formatting of a Research Paper

• For example: “Growing up Stronger: Why Girls’ Schools Create More Confident Women” is more interesting and concise than “Single-Sex Schools are Better than Co-Ed Schools at Developing Self Confidence for Girls.”

• The author should clearly identify any ideas that are not their own and reference other works that make up the research landscape for context.
• Common style guides for research papers include the APA style guide, the Chicago Manual of Style, the MLA Handbook, and the Turabian citation guide.

12.7 Evaluation: Effectiveness of Research Paper

Learning outcomes.

By the end of this section, you will be able to:

• Identify common formats and design features for different kinds of texts.
• Implement style and language consistent with argumentative research writing while maintaining your own voice.
• Determine how genre conventions for structure, paragraphing, tone, and mechanics vary.

When drafting, you follow your strongest research interests and try to answer the question on which you have settled. However, sometimes what began as a paper about one thing becomes a paper about something else. Your peer review partner will have helped you identify any such issues and given you some insight regarding revision. Another strategy is to compare and contrast your draft with the grading rubric similar to one your instructor will use. It is a good idea to consult this rubric frequently throughout the drafting process.

1 Important points to consider when critically evaluating published research papers

Simple review articles (also referred to as ‘narrative’ or ‘selective’ reviews), systematic reviews and meta-analyses provide rapid overviews and ‘snapshots’ of progress made within a field, summarising a given topic or research area. They can serve as useful guides, or as current and comprehensive ‘sources’ of information, and can act as a point of reference to relevant primary research studies within a given scientific area. Narrative or systematic reviews are often used as a first step towards a more detailed investigation of a topic or a specific enquiry (a hypothesis or research question), or to establish critical awareness of a rapidly-moving field (you will be required to demonstrate this as part of an assignment, an essay or a dissertation at postgraduate level).

The majority of primary ‘empirical’ research papers essentially follow the same structure (abbreviated here as IMRAD). There is a section on Introduction, followed by the Methods, then the Results, which includes figures and tables showing data described in the paper, and a Discussion. The paper typically ends with a Conclusion, and References and Acknowledgements sections.

The Title of the paper provides a concise first impression. The Abstract follows the basic structure of the extended article. It provides an ‘accessible’ and concise summary of the aims, methods, results and conclusions. The Introduction provides useful background information and context, and typically outlines the aims and objectives of the study. The Abstract can serve as a useful summary of the paper, presenting the purpose, scope and major findings. However, simply reading the abstract alone is not a substitute for critically reading the whole article. To really get a good understanding and to be able to critically evaluate a research study, it is necessary to read on.

While most research papers follow the above format, variations do exist. For example, the results and discussion sections may be combined. In some journals the materials and methods may follow the discussion, and in two of the most widely read journals, Science and Nature, the format does vary from the above due to restrictions on the length of articles. In addition, there may be supporting documents that accompany a paper, including supplementary materials such as supporting data, tables, figures, videos and so on. There may also be commentaries or editorials associated with a topical research paper, which provide an overview or critique of the study being presented.

Box 1 Key questions to ask when appraising a research paper

• Is the study’s research question relevant?
• Does the study add anything new to current knowledge and understanding?
• Does the study test a stated hypothesis?
• Is the design of the study appropriate to the research question?
• Do the study methods address key potential sources of bias?
• Were suitable ‘controls’ included in the study?
• Were the statistical analyses appropriate and applied correctly?
• Is there a clear statement of findings?
• Does the data support the authors’ conclusions?
• Are there any conflicts of interest or ethical concerns?

There are various strategies used in reading a scientific research paper, and one of these is to start with the title and the abstract, then look at the figures and tables, and move on to the introduction, before turning to the results and discussion, and finally, interrogating the methods.

Another strategy (outlined below) is to begin with the abstract and then the discussion, take a look at the methods, and then the results section (including any relevant tables and figures), before moving on to look more closely at the discussion and, finally, the conclusion. You should choose a strategy that works best for you. However, asking the ‘right’ questions is a central feature of critical appraisal, as with any enquiry, so where should you begin? Here are some critical questions to consider when evaluating a research paper.

Look at the Abstract and then the Discussion : Are these accessible and of general relevance or are they detailed, with far-reaching conclusions? Is it clear why the study was undertaken? Why are the conclusions important? Does the study add anything new to current knowledge and understanding? The reasons why a particular study design or statistical method were chosen should also be clear from reading a research paper. What is the research question being asked? Does the study test a stated hypothesis? Is the design of the study appropriate to the research question? Have the authors considered the limitations of their study and have they discussed these in context?

Take a look at the Methods : Were there any practical difficulties that could have compromised the study or its implementation? Were these considered in the protocol? Were there any missing values and, if so, was the number of missing values too large to permit meaningful analysis? Was the number of samples (cases or participants) too small to establish meaningful significance? Do the study methods address key potential sources of bias? Were suitable ‘controls’ included in the study? If controls are missing or not appropriate to the study design, we cannot be confident that the results really show what is happening in an experiment. Were the statistical analyses appropriate and applied correctly? Do the authors point out the limitations of methods or tests used? Were the methods referenced and described in sufficient detail for others to repeat or extend the study?

Take a look at the Results section and relevant tables and figures : Is there a clear statement of findings? Were the results expected? Do they make sense? What data supports them? Do the tables and figures clearly describe the data (highlighting trends etc.)? Try to distinguish between what the data show and what the authors say they show (i.e. their interpretation).

Moving on to look in greater depth at the Discussion and Conclusion : Are the results discussed in relation to similar (previous) studies? Do the authors indulge in excessive speculation? Are limitations of the study adequately addressed? Were the objectives of the study met and the hypothesis supported or refuted (and is a clear explanation provided)? Does the data support the authors’ conclusions? Maybe there is only one experiment to support a point. More often, several different experiments or approaches combine to support a particular conclusion. A rule of thumb here is that if multiple approaches and multiple lines of evidence from different directions are presented, and all point to the same conclusion, then the conclusions are more credible. But do question all assumptions. Identify any implicit or hidden assumptions that the authors may have used when interpreting their data. Be wary of data that is mixed up with interpretation and speculation! Remember, just because it is published, does not mean that it is right.

O ther points you should consider when evaluating a research paper : Are there any financial, ethical or other conflicts of interest associated with the study, its authors and sponsors? Are there ethical concerns with the study itself? Looking at the references, consider if the authors have preferentially cited their own previous publications (i.e. needlessly), and whether the list of references are recent (ensuring that the analysis is up-to-date). Finally, from a practical perspective, you should move beyond the text of a research paper, talk to your peers about it, consult available commentaries, online links to references and other external sources to help clarify any aspects you don’t understand.

The above can be taken as a general guide to help you begin to critically evaluate a scientific research paper, but only in the broadest sense. Do bear in mind that the way that research evidence is critiqued will also differ slightly according to the type of study being appraised, whether observational or experimental, and each study will have additional aspects that would need to be evaluated separately. For criteria recommended for the evaluation of qualitative research papers, see the article by Mildred Blaxter (1996), available online. Details are in the References.

Activity 1 Critical appraisal of a scientific research paper

A critical appraisal checklist, which you can download via the link below, can act as a useful tool to help you to interrogate research papers. The checklist is divided into four sections, broadly covering:

• some general aspects
• research design and methodology
• the results
• discussion, conclusion and references.

Science perspective – critical appraisal checklist [ Tip: hold Ctrl and click a link to open it in a new tab. ( Hide tip ) ]

• Identify and obtain a research article based on a topic of your own choosing, using a search engine such as Google Scholar or PubMed (for example).
• The selection criteria for your target paper are as follows: the article must be an open access primary research paper (not a review) containing empirical data, published in the last 2–3 years, and preferably no more than 5–6 pages in length.
• Critically evaluate the research paper using the checklist provided, making notes on the key points and your overall impression.

Critical appraisal checklists are useful tools to help assess the quality of a study. Assessment of various factors, including the importance of the research question, the design and methodology of a study, the validity of the results and their usefulness (application or relevance), the legitimacy of the conclusions, and any potential conflicts of interest, are an important part of the critical appraisal process. Limitations and further improvements can then be considered.

When you receive an invitation to peer review, you should be sent a copy of the paper's abstract to help you decide whether you wish to do the review. Try to respond to invitations promptly - it will prevent delays. It is also important at this stage to declare any potential Conflict of Interest.

The structure of the review report varies between journals. Some follow an informal structure, while others have a more formal approach.

" Number your comments!!! " (Jonathon Halbesleben, former Editor of Journal of Occupational and Organizational Psychology)

Informal Structure

Many journals don't provide criteria for reviews beyond asking for your 'analysis of merits'. In this case, you may wish to familiarize yourself with examples of other reviews done for the journal, which the editor should be able to provide or, as you gain experience, rely on your own evolving style.

Formal Structure

Other journals require a more formal approach. Sometimes they will ask you to address specific questions in your review via a questionnaire. Or they might want you to rate the manuscript on various attributes using a scorecard. Often you can't see these until you log in to submit your review. So when you agree to the work, it's worth checking for any journal-specific guidelines and requirements. If there are formal guidelines, let them direct the structure of your review.

In Both Cases

Whether specifically required by the reporting format or not, you should expect to compile comments to authors and possibly confidential ones to editors only.

Following the invitation to review, when you'll have received the article abstract, you should already understand the aims, key data and conclusions of the manuscript. If you don't, make a note now that you need to feedback on how to improve those sections.

The first read-through is a skim-read. It will help you form an initial impression of the paper and get a sense of whether your eventual recommendation will be to accept or reject the paper.

Keep a pen and paper handy when skim-reading.

Try to bear in mind the following questions - they'll help you form your overall impression:

• What is the main question addressed by the research? Is it relevant and interesting?
• How original is the topic? What does it add to the subject area compared with other published material?
• Is the paper well written? Is the text clear and easy to read?
• Are the conclusions consistent with the evidence and arguments presented? Do they address the main question posed?
• If the author is disagreeing significantly with the current academic consensus, do they have a substantial case? If not, what would be required to make their case credible?
• If the paper includes tables or figures, what do they add to the paper? Do they aid understanding or are they superfluous?

While you should read the whole paper, making the right choice of what to read first can save time by flagging major problems early on.

Editors say, " Specific recommendations for remedying flaws are VERY welcome ."

Examples of possibly major flaws include:

• Drawing a conclusion that is contradicted by the author's own statistical or qualitative evidence
• The use of a discredited method
• Ignoring a process that is known to have a strong influence on the area under study

If experimental design features prominently in the paper, first check that the methodology is sound - if not, this is likely to be a major flaw.

You might examine:

• The sampling in analytical papers
• The sufficient use of control experiments
• The precision of process data
• The regularity of sampling in time-dependent studies
• The validity of questions, the use of a detailed methodology and the data analysis being done systematically (in qualitative research)
• That qualitative research extends beyond the author's opinions, with sufficient descriptive elements and appropriate quotes from interviews or focus groups

Major Flaws in Information

If methodology is less of an issue, it's often a good idea to look at the data tables, figures or images first. Especially in science research, it's all about the information gathered. If there are critical flaws in this, it's very likely the manuscript will need to be rejected. Such issues include:

• Insufficient data
• Unclear data tables
• Contradictory data that either are not self-consistent or disagree with the conclusions
• Confirmatory data that adds little, if anything, to current understanding - unless strong arguments for such repetition are made

If you find a major problem, note your reasoning and clear supporting evidence (including citations).

After the initial read and using your notes, including those of any major flaws you found, draft the first two paragraphs of your review - the first summarizing the research question addressed and the second the contribution of the work. If the journal has a prescribed reporting format, this draft will still help you compose your thoughts.

The First Paragraph

This should state the main question addressed by the research and summarize the goals, approaches, and conclusions of the paper. It should:

• Help the editor properly contextualize the research and add weight to your judgement
• Show the author what key messages are conveyed to the reader, so they can be sure they are achieving what they set out to do
• Focus on successful aspects of the paper so the author gets a sense of what they've done well

The Second Paragraph

This should provide a conceptual overview of the contribution of the research. So consider:

• Is the paper's premise interesting and important?
• Are the methods used appropriate?
• Do the data support the conclusions?

After drafting these two paragraphs, you should be in a position to decide whether this manuscript is seriously flawed and should be rejected (see the next section). Or whether it is publishable in principle and merits a detailed, careful read through.

Even if you are coming to the opinion that an article has serious flaws, make sure you read the whole paper. This is very important because you may find some really positive aspects that can be communicated to the author. This could help them with future submissions.

A full read-through will also make sure that any initial concerns are indeed correct and fair. After all, you need the context of the whole paper before deciding to reject. If you still intend to recommend rejection, see the section "When recommending rejection."

Once the paper has passed your first read and you've decided the article is publishable in principle, one purpose of the second, detailed read-through is to help prepare the manuscript for publication. You may still decide to recommend rejection following a second reading.

" Offer clear suggestions for how the authors can address the concerns raised. In other words, if you're going to raise a problem, provide a solution ." (Jonathon Halbesleben, Editor of Journal of Occupational and Organizational Psychology)

Preparation

To save time and simplify the review:

• Don't rely solely upon inserting comments on the manuscript document - make separate notes
• Try to group similar concerns or praise together
• If using a review program to note directly onto the manuscript, still try grouping the concerns and praise in separate notes - it helps later
• Note line numbers of text upon which your notes are based - this helps you find items again and also aids those reading your review

Now that you have completed your preparations, you're ready to spend an hour or so reading carefully through the manuscript.

As you're reading through the manuscript for a second time, you'll need to keep in mind the argument's construction, the clarity of the language and content.

With regard to the argument’s construction, you should identify:

• Any places where the meaning is unclear or ambiguous
• Any factual errors
• Any invalid arguments

You may also wish to consider:

• Does the title properly reflect the subject of the paper?
• Does the abstract provide an accessible summary of the paper?
• Do the keywords accurately reflect the content?
• Is the paper an appropriate length?
• Are the key messages short, accurate and clear?

Not every submission is well written. Part of your role is to make sure that the text’s meaning is clear.

Editors say, " If a manuscript has many English language and editing issues, please do not try and fix it. If it is too bad, note that in your review and it should be up to the authors to have the manuscript edited ."

If the article is difficult to understand, you should have rejected it already. However, if the language is poor but you understand the core message, see if you can suggest improvements to fix the problem:

• Are there certain aspects that could be communicated better, such as parts of the discussion?
• Should the authors consider resubmitting to the same journal after language improvements?
• Would you consider looking at the paper again once these issues are dealt with?

On Grammar and Punctuation

Your primary role is judging the research content. Don't spend time polishing grammar or spelling. Editors will make sure that the text is at a high standard before publication. However, if you spot grammatical errors that affect clarity of meaning, then it's important to highlight these. Expect to suggest such amendments - it's rare for a manuscript to pass review with no corrections.

A 2010 study of nursing journals found that 79% of recommendations by reviewers were influenced by grammar and writing style (Shattel, et al., 2010).

1. The Introduction

A well-written introduction:

• Sets out the argument
• Summarizes recent research related to the topic
• Highlights gaps in current understanding or conflicts in current knowledge
• Establishes the originality of the research aims by demonstrating the need for investigations in the topic area
• Gives a clear idea of the target readership, why the research was carried out and the novelty and topicality of the manuscript

Originality and Topicality

Originality and topicality can only be established in the light of recent authoritative research. For example, it's impossible to argue that there is a conflict in current understanding by referencing articles that are 10 years old.

Authors may make the case that a topic hasn't been investigated in several years and that new research is required. This point is only valid if researchers can point to recent developments in data gathering techniques or to research in indirectly related fields that suggest the topic needs revisiting. Clearly, authors can only do this by referencing recent literature. Obviously, where older research is seminal or where aspects of the methodology rely upon it, then it is perfectly appropriate for authors to cite some older papers.

Editors say, "Is the report providing new information; is it novel or just confirmatory of well-known outcomes ?"

It's common for the introduction to end by stating the research aims. By this point you should already have a good impression of them - if the explicit aims come as a surprise, then the introduction needs improvement.

2. Materials and Methods

Academic research should be replicable, repeatable and robust - and follow best practice.

Replicable Research

This makes sufficient use of:

• Control experiments
• Repeated analyses
• Repeated experiments

These are used to make sure observed trends are not due to chance and that the same experiment could be repeated by other researchers - and result in the same outcome. Statistical analyses will not be sound if methods are not replicable. Where research is not replicable, the paper should be recommended for rejection.

Repeatable Methods

These give enough detail so that other researchers are able to carry out the same research. For example, equipment used or sampling methods should all be described in detail so that others could follow the same steps. Where methods are not detailed enough, it's usual to ask for the methods section to be revised.

Robust Research

This has enough data points to make sure the data are reliable. If there are insufficient data, it might be appropriate to recommend revision. You should also consider whether there is any in-built bias not nullified by the control experiments.

Best Practice

During these checks you should keep in mind best practice:

• Standard guidelines were followed (e.g. the CONSORT Statement for reporting randomized trials)
• The health and safety of all participants in the study was not compromised
• Ethical standards were maintained

If the research fails to reach relevant best practice standards, it's usual to recommend rejection. What's more, you don't then need to read any further.

3. Results and Discussion

This section should tell a coherent story - What happened? What was discovered or confirmed?

Certain patterns of good reporting need to be followed by the author:

• They should start by describing in simple terms what the data show
• They should make reference to statistical analyses, such as significance or goodness of fit
• Once described, they should evaluate the trends observed and explain the significance of the results to wider understanding. This can only be done by referencing published research
• The outcome should be a critical analysis of the data collected

Discussion should always, at some point, gather all the information together into a single whole. Authors should describe and discuss the overall story formed. If there are gaps or inconsistencies in the story, they should address these and suggest ways future research might confirm the findings or take the research forward.

4. Conclusions

This section is usually no more than a few paragraphs and may be presented as part of the results and discussion, or in a separate section. The conclusions should reflect upon the aims - whether they were achieved or not - and, just like the aims, should not be surprising. If the conclusions are not evidence-based, it's appropriate to ask for them to be re-written.

5. Information Gathered: Images, Graphs and Data Tables

If you find yourself looking at a piece of information from which you cannot discern a story, then you should ask for improvements in presentation. This could be an issue with titles, labels, statistical notation or image quality.

Where information is clear, you should check that:

• The results seem plausible, in case there is an error in data gathering
• The trends you can see support the paper's discussion and conclusions
• There are sufficient data. For example, in studies carried out over time are there sufficient data points to support the trends described by the author?

You should also check whether images have been edited or manipulated to emphasize the story they tell. This may be appropriate but only if authors report on how the image has been edited (e.g. by highlighting certain parts of an image). Where you feel that an image has been edited or manipulated without explanation, you should highlight this in a confidential comment to the editor in your report.

6. List of References

You will need to check referencing for accuracy, adequacy and balance.

Where a cited article is central to the author's argument, you should check the accuracy and format of the reference - and bear in mind different subject areas may use citations differently. Otherwise, it's the editor’s role to exhaustively check the reference section for accuracy and format.

You should consider if the referencing is adequate:

• Are important parts of the argument poorly supported?
• Are there published studies that show similar or dissimilar trends that should be discussed?
• If a manuscript only uses half the citations typical in its field, this may be an indicator that referencing should be improved - but don't be guided solely by quantity
• References should be relevant, recent and readily retrievable

Check for a well-balanced list of references that is:

• Helpful to the reader
• Fair to competing authors
• Not over-reliant on self-citation
• Gives due recognition to the initial discoveries and related work that led to the work under assessment

You should be able to evaluate whether the article meets the criteria for balanced referencing without looking up every reference.

7. Plagiarism

By now you will have a deep understanding of the paper's content - and you may have some concerns about plagiarism.

Identified Concern

If you find - or already knew of - a very similar paper, this may be because the author overlooked it in their own literature search. Or it may be because it is very recent or published in a journal slightly outside their usual field.

You may feel you can advise the author how to emphasize the novel aspects of their own study, so as to better differentiate it from similar research. If so, you may ask the author to discuss their aims and results, or modify their conclusions, in light of the similar article. Of course, the research similarities may be so great that they render the work unoriginal and you have no choice but to recommend rejection.

"It's very helpful when a reviewer can point out recent similar publications on the same topic by other groups, or that the authors have already published some data elsewhere ." (Editor feedback)

Suspected Concern

If you suspect plagiarism, including self-plagiarism, but cannot recall or locate exactly what is being plagiarized, notify the editor of your suspicion and ask for guidance.

Most editors have access to software that can check for plagiarism.

Editors are not out to police every paper, but when plagiarism is discovered during peer review it can be properly addressed ahead of publication. If plagiarism is discovered only after publication, the consequences are worse for both authors and readers, because a retraction may be necessary.

For detailed guidelines see COPE's Ethical guidelines for reviewers and Wiley's Best Practice Guidelines on Publishing Ethics .

8. Search Engine Optimization (SEO)

After the detailed read-through, you will be in a position to advise whether the title, abstract and key words are optimized for search purposes. In order to be effective, good SEO terms will reflect the aims of the research.

A clear title and abstract will improve the paper's search engine rankings and will influence whether the user finds and then decides to navigate to the main article. The title should contain the relevant SEO terms early on. This has a major effect on the impact of a paper, since it helps it appear in search results. A poor abstract can then lose the reader's interest and undo the benefit of an effective title - whilst the paper's abstract may appear in search results, the potential reader may go no further.

So ask yourself, while the abstract may have seemed adequate during earlier checks, does it:

• Do justice to the manuscript in this context?
• Highlight important findings sufficiently?
• Present the most interesting data?

Editors say, " Does the Abstract highlight the important findings of the study ?"

If there is a formal report format, remember to follow it. This will often comprise a range of questions followed by comment sections. Try to answer all the questions. They are there because the editor felt that they are important. If you're following an informal report format you could structure your report in three sections: summary, major issues, minor issues.

• Give positive feedback first. Authors are more likely to read your review if you do so. But don't overdo it if you will be recommending rejection
• Briefly summarize what the paper is about and what the findings are
• Try to put the findings of the paper into the context of the existing literature and current knowledge
• Indicate the significance of the work and if it is novel or mainly confirmatory
• Indicate the work's strengths, its quality and completeness
• State any major flaws or weaknesses and note any special considerations. For example, if previously held theories are being overlooked

Major Issues

• Are there any major flaws? State what they are and what the severity of their impact is on the paper
• Has similar work already been published without the authors acknowledging this?
• Are the authors presenting findings that challenge current thinking? Is the evidence they present strong enough to prove their case? Have they cited all the relevant work that would contradict their thinking and addressed it appropriately?
• If major revisions are required, try to indicate clearly what they are
• Are there any major presentational problems? Are figures & tables, language and manuscript structure all clear enough for you to accurately assess the work?
• Are there any ethical issues? If you are unsure it may be better to disclose these in the confidential comments section

Minor Issues

• Are there places where meaning is ambiguous? How can this be corrected?
• Are the correct references cited? If not, which should be cited instead/also? Are citations excessive, limited, or biased?
• Are there any factual, numerical or unit errors? If so, what are they?
• Are all tables and figures appropriate, sufficient, and correctly labelled? If not, say which are not

Your review should ultimately help the author improve their article. So be polite, honest and clear. You should also try to be objective and constructive, not subjective and destructive.

You should also:

• Write clearly and so you can be understood by people whose first language is not English
• Avoid complex or unusual words, especially ones that would even confuse native speakers
• Number your points and refer to page and line numbers in the manuscript when making specific comments
• If you have been asked to only comment on specific parts or aspects of the manuscript, you should indicate clearly which these are
• Treat the author's work the way you would like your own to be treated

Most journals give reviewers the option to provide some confidential comments to editors. Often this is where editors will want reviewers to state their recommendation - see the next section - but otherwise this area is best reserved for communicating malpractice such as suspected plagiarism, fraud, unattributed work, unethical procedures, duplicate publication, bias or other conflicts of interest.

However, this doesn't give reviewers permission to 'backstab' the author. Authors can't see this feedback and are unable to give their side of the story unless the editor asks them to. So in the spirit of fairness, write comments to editors as though authors might read them too.

Reviewers should check the preferences of individual journals as to where they want review decisions to be stated. In particular, bear in mind that some journals will not want the recommendation included in any comments to authors, as this can cause editors difficulty later - see Section 11 for more advice about working with editors.

You will normally be asked to indicate your recommendation (e.g. accept, reject, revise and resubmit, etc.) from a fixed-choice list and then to enter your comments into a separate text box.

Recommending Acceptance

If you're recommending acceptance, give details outlining why, and if there are any areas that could be improved. Don't just give a short, cursory remark such as 'great, accept'. See Improving the Manuscript

Recommending Revision

Where improvements are needed, a recommendation for major or minor revision is typical. You may also choose to state whether you opt in or out of the post-revision review too. If recommending revision, state specific changes you feel need to be made. The author can then reply to each point in turn.

Some journals offer the option to recommend rejection with the possibility of resubmission – this is most relevant where substantial, major revision is necessary.

What can reviewers do to help? " Be clear in their comments to the author (or editor) which points are absolutely critical if the paper is given an opportunity for revisio n." (Jonathon Halbesleben, Editor of Journal of Occupational and Organizational Psychology)

Recommending Rejection

If recommending rejection or major revision, state this clearly in your review (and see the next section, 'When recommending rejection').

Where manuscripts have serious flaws you should not spend any time polishing the review you've drafted or give detailed advice on presentation.

Editors say, " If a reviewer suggests a rejection, but her/his comments are not detailed or helpful, it does not help the editor in making a decision ."

In your recommendations for the author, you should:

• Give constructive feedback describing ways that they could improve the research
• Keep the focus on the research and not the author. This is an extremely important part of your job as a reviewer
• Avoid making critical confidential comments to the editor while being polite and encouraging to the author - the latter may not understand why their manuscript has been rejected. Also, they won't get feedback on how to improve their research and it could trigger an appeal

Remember to give constructive criticism even if recommending rejection. This helps developing researchers improve their work and explains to the editor why you felt the manuscript should not be published.

" When the comments seem really positive, but the recommendation is rejection…it puts the editor in a tough position of having to reject a paper when the comments make it sound like a great paper ." (Jonathon Halbesleben, Editor of Journal of Occupational and Organizational Psychology)

How Will This Help Me?

Evaluating your sources will help you:

• Determine the credibility of information
• Rule out questionable information
• Check for bias in your sources

In general, websites are hosted in domains that tell you what type of site it is.

• .com = commercial
• .net = network provider
• .org = organization
• .edu = education
• .mil = military
• .gov = U.S. government

Commercial sites want to persuade you to buy something, and organizations may want to persuade you to see an issue from a particular viewpoint. 

Useful information can be found on all kinds of sites, but you must consider carefully whether the source is useful for your purpose and for your audience.

Content Farms

Content farms are websites that exist to host ads. They post about popular web searches to try to drive traffic to their sites. They are rarely good sources for research.

• Web’s “Content Farms” Grow Audiences For Ads This article by Zoe Chace at National Public Radio describes the ways How To sites try to drive more traffic to their sites to see the ads they host.

Fact Checking

Fact checking can help you verify the reliability of a source. The following sites may not have all the answers, but they can help you look into the sources for statements made in U.S. politics.

• FactCheck.org This site monitors the accuracy of statements made in speeches, debates, interviews, and more and links to sources so readers can see the information for themselves. The site is a project of the Annenberg Public Policy Center of the University of Pennsylvania.
• PolitiFact This resource evaluates the accuracy of statements made by elected officials, lobbyists, and special interest groups and provides sources for their evaluations. PolitiFact is currently run by the nonprofit Poynter Institute for Media Studies.

Evaluate Sources With the Big 5 Criteria

The Big 5 Criteria can help you evaluate your sources for credibility:

• Currency: Check the publication date and determine whether it is sufficiently current for your topic.
• Coverage (relevance): Consider whether the source is relevant to your research and whether it covers the topic adequately for your needs.
• Authority: Discover the credentials of the authors of the source and determine their level of expertise and knowledge about the subject.
• Accuracy: Consider whether the source presents accurate information and whether you can verify that information. 
• Objectivity (purpose): Think about the author's purpose in creating the source and consider how that affects its usefulness to your research. 

Evaluate Sources With the CRAAP Test

Another way to evaluate your sources is the CRAAP Test, which means evaluating the following qualities of your sources:

Evaluate Websites

Evaluating websites follows the same process as for other sources, but finding the information you need to make an assessment can be more challenging with websites. The following guidelines can help you decide if a website is a good choice for a source for your paper. 

• Currency . A useful site is updated regularly and lets visitors know when content was published on the site. Can you tell when the site was last updated? Can you see when the content you need was added? Does the site show signs of not being maintained (broken links, out-of-date information, etc.)?
• Relevance . Think about the target audience for the site. Is it appropriate for you or your paper's audience?
• Authority . Look for an About Us link or something similar to learn about the site's creator. The more you know about the credentials and mission of a site's creators, as well as their sources of information, the better idea you will have about the site's quality. 
• Accuracy. Does the site present references or links to the sources of information it presents? Can you locate these sources so that you can read and interpret the information yourself?
• Purpose. Consider the reason why the site was created. Can you detect any bias? Does the site use emotional language? Is the site trying to persuade you about something? 

Identify Political Perspective

News outlets, think tanks, organizations, and individual authors can present information from a particular political perspective. Consider this fact to help determine whether sources are useful for your paper. 

Check a news outlet's website, usually under About Us or Contact Us , for information about their reporters and authors. For example, USA Today has the USA Today Reporter Index , and the LA Times has an Editorial & Newsroom Contacts . Reading a profile or bio for a reporter or looking at other articles by the author may tell you whether that person favors a particular viewpoint. 

If a particular organization is mentioned in an article, learn more about the organization to identify potential biases. Think tanks and other associations usually exist for a reason. Searching news articles about the organization can help you determine their political leaning. 

Bias is not always bad, but you must be aware of it. Knowing the perspective of a source helps contextualize the information presented.

• How to Write Discussions and Conclusions

The discussion section contains the results and outcomes of a study. An effective discussion informs readers what can be learned from your experiment and provides context for the results.

What makes an effective discussion?

When you’re ready to write your discussion, you’ve already introduced the purpose of your study and provided an in-depth description of the methodology. The discussion informs readers about the larger implications of your study based on the results. Highlighting these implications while not overstating the findings can be challenging, especially when you’re submitting to a journal that selects articles based on novelty or potential impact. Regardless of what journal you are submitting to, the discussion section always serves the same purpose: concluding what your study results actually mean.

A successful discussion section puts your findings in context. It should include:

• the results of your research,
• a discussion of related research, and
• a comparison between your results and initial hypothesis.

Tip: Not all journals share the same naming conventions.

You can apply the advice in this article to the conclusion, results or discussion sections of your manuscript.

Our Early Career Researcher community tells us that the conclusion is often considered the most difficult aspect of a manuscript to write. To help, this guide provides questions to ask yourself, a basic structure to model your discussion off of and examples from published manuscripts. 

Questions to ask yourself:

• Was my hypothesis correct?
• If my hypothesis is partially correct or entirely different, what can be learned from the results? 
• How do the conclusions reshape or add onto the existing knowledge in the field? What does previous research say about the topic? 
• Why are the results important or relevant to your audience? Do they add further evidence to a scientific consensus or disprove prior studies? 
• How can future research build on these observations? What are the key experiments that must be done? 
• What is the “take-home” message you want your reader to leave with?

How to structure a discussion

Trying to fit a complete discussion into a single paragraph can add unnecessary stress to the writing process. If possible, you’ll want to give yourself two or three paragraphs to give the reader a comprehensive understanding of your study as a whole. Here’s one way to structure an effective discussion:

Writing Tips

While the above sections can help you brainstorm and structure your discussion, there are many common mistakes that writers revert to when having difficulties with their paper. Writing a discussion can be a delicate balance between summarizing your results, providing proper context for your research and avoiding introducing new information. Remember that your paper should be both confident and honest about the results! 

• Read the journal’s guidelines on the discussion and conclusion sections. If possible, learn about the guidelines before writing the discussion to ensure you’re writing to meet their expectations. 
• Begin with a clear statement of the principal findings. This will reinforce the main take-away for the reader and set up the rest of the discussion. 
• Explain why the outcomes of your study are important to the reader. Discuss the implications of your findings realistically based on previous literature, highlighting both the strengths and limitations of the research. 
• State whether the results prove or disprove your hypothesis. If your hypothesis was disproved, what might be the reasons? 
• Introduce new or expanded ways to think about the research question. Indicate what next steps can be taken to further pursue any unresolved questions. 
• If dealing with a contemporary or ongoing problem, such as climate change, discuss possible consequences if the problem is avoided. 
• Be concise. Adding unnecessary detail can distract from the main findings. 

Don’t

• Rewrite your abstract. Statements with “we investigated” or “we studied” generally do not belong in the discussion. 
• Include new arguments or evidence not previously discussed. Necessary information and evidence should be introduced in the main body of the paper. 
• Apologize. Even if your research contains significant limitations, don’t undermine your authority by including statements that doubt your methodology or execution. 
• Shy away from speaking on limitations or negative results. Including limitations and negative results will give readers a complete understanding of the presented research. Potential limitations include sources of potential bias, threats to internal or external validity, barriers to implementing an intervention and other issues inherent to the study design. 
• Overstate the importance of your findings. Making grand statements about how a study will fully resolve large questions can lead readers to doubt the success of the research.

A Practical Guide to Writing Quantitative and Qualitative Research Questions and Hypotheses in Scholarly Articles

The development of research questions and the subsequent hypotheses are prerequisites to defining the main research purpose and specific objectives of a study. Consequently, these objectives determine the study design and research outcome. The development of research questions is a process based on knowledge of current trends, cutting-edge studies, and technological advances in the research field. Excellent research questions are focused and require a comprehensive literature search and in-depth understanding of the problem being investigated. Initially, research questions may be written as descriptive questions which could be developed into inferential questions. These questions must be specific and concise to provide a clear foundation for developing hypotheses. Hypotheses are more formal predictions about the research outcomes. These specify the possible results that may or may not be expected regarding the relationship between groups. Thus, research questions and hypotheses clarify the main purpose and specific objectives of the study, which in turn dictate the design of the study, its direction, and outcome. Studies developed from good research questions and hypotheses will have trustworthy outcomes with wide-ranging social and health implications.

INTRODUCTION

Scientific research is usually initiated by posing evidenced-based research questions which are then explicitly restated as hypotheses. 1 , 2 The hypotheses provide directions to guide the study, solutions, explanations, and expected results. 3 , 4 Both research questions and hypotheses are essentially formulated based on conventional theories and real-world processes, which allow the inception of novel studies and the ethical testing of ideas. 5 , 6

It is crucial to have knowledge of both quantitative and qualitative research 2 as both types of research involve writing research questions and hypotheses. 7 However, these crucial elements of research are sometimes overlooked; if not overlooked, then framed without the forethought and meticulous attention it needs. Planning and careful consideration are needed when developing quantitative or qualitative research, particularly when conceptualizing research questions and hypotheses. 4

There is a continuing need to support researchers in the creation of innovative research questions and hypotheses, as well as for journal articles that carefully review these elements. 1 When research questions and hypotheses are not carefully thought of, unethical studies and poor outcomes usually ensue. Carefully formulated research questions and hypotheses define well-founded objectives, which in turn determine the appropriate design, course, and outcome of the study. This article then aims to discuss in detail the various aspects of crafting research questions and hypotheses, with the goal of guiding researchers as they develop their own. Examples from the authors and peer-reviewed scientific articles in the healthcare field are provided to illustrate key points.

DEFINITIONS AND RELATIONSHIP OF RESEARCH QUESTIONS AND HYPOTHESES

A research question is what a study aims to answer after data analysis and interpretation. The answer is written in length in the discussion section of the paper. Thus, the research question gives a preview of the different parts and variables of the study meant to address the problem posed in the research question. 1 An excellent research question clarifies the research writing while facilitating understanding of the research topic, objective, scope, and limitations of the study. 5

On the other hand, a research hypothesis is an educated statement of an expected outcome. This statement is based on background research and current knowledge. 8 , 9 The research hypothesis makes a specific prediction about a new phenomenon 10 or a formal statement on the expected relationship between an independent variable and a dependent variable. 3 , 11 It provides a tentative answer to the research question to be tested or explored. 4

Hypotheses employ reasoning to predict a theory-based outcome. 10 These can also be developed from theories by focusing on components of theories that have not yet been observed. 10 The validity of hypotheses is often based on the testability of the prediction made in a reproducible experiment. 8

Conversely, hypotheses can also be rephrased as research questions. Several hypotheses based on existing theories and knowledge may be needed to answer a research question. Developing ethical research questions and hypotheses creates a research design that has logical relationships among variables. These relationships serve as a solid foundation for the conduct of the study. 4 , 11 Haphazardly constructed research questions can result in poorly formulated hypotheses and improper study designs, leading to unreliable results. Thus, the formulations of relevant research questions and verifiable hypotheses are crucial when beginning research. 12

CHARACTERISTICS OF GOOD RESEARCH QUESTIONS AND HYPOTHESES

Excellent research questions are specific and focused. These integrate collective data and observations to confirm or refute the subsequent hypotheses. Well-constructed hypotheses are based on previous reports and verify the research context. These are realistic, in-depth, sufficiently complex, and reproducible. More importantly, these hypotheses can be addressed and tested. 13

There are several characteristics of well-developed hypotheses. Good hypotheses are 1) empirically testable 7 , 10 , 11 , 13 ; 2) backed by preliminary evidence 9 ; 3) testable by ethical research 7 , 9 ; 4) based on original ideas 9 ; 5) have evidenced-based logical reasoning 10 ; and 6) can be predicted. 11 Good hypotheses can infer ethical and positive implications, indicating the presence of a relationship or effect relevant to the research theme. 7 , 11 These are initially developed from a general theory and branch into specific hypotheses by deductive reasoning. In the absence of a theory to base the hypotheses, inductive reasoning based on specific observations or findings form more general hypotheses. 10

TYPES OF RESEARCH QUESTIONS AND HYPOTHESES

Research questions and hypotheses are developed according to the type of research, which can be broadly classified into quantitative and qualitative research. We provide a summary of the types of research questions and hypotheses under quantitative and qualitative research categories in Table 1 .

Research questions in quantitative research

In quantitative research, research questions inquire about the relationships among variables being investigated and are usually framed at the start of the study. These are precise and typically linked to the subject population, dependent and independent variables, and research design. 1 Research questions may also attempt to describe the behavior of a population in relation to one or more variables, or describe the characteristics of variables to be measured ( descriptive research questions ). 1 , 5 , 14 These questions may also aim to discover differences between groups within the context of an outcome variable ( comparative research questions ), 1 , 5 , 14 or elucidate trends and interactions among variables ( relationship research questions ). 1 , 5 We provide examples of descriptive, comparative, and relationship research questions in quantitative research in Table 2 .

Hypotheses in quantitative research

In quantitative research, hypotheses predict the expected relationships among variables. 15 Relationships among variables that can be predicted include 1) between a single dependent variable and a single independent variable ( simple hypothesis ) or 2) between two or more independent and dependent variables ( complex hypothesis ). 4 , 11 Hypotheses may also specify the expected direction to be followed and imply an intellectual commitment to a particular outcome ( directional hypothesis ) 4 . On the other hand, hypotheses may not predict the exact direction and are used in the absence of a theory, or when findings contradict previous studies ( non-directional hypothesis ). 4 In addition, hypotheses can 1) define interdependency between variables ( associative hypothesis ), 4 2) propose an effect on the dependent variable from manipulation of the independent variable ( causal hypothesis ), 4 3) state a negative relationship between two variables ( null hypothesis ), 4 , 11 , 15 4) replace the working hypothesis if rejected ( alternative hypothesis ), 15 explain the relationship of phenomena to possibly generate a theory ( working hypothesis ), 11 5) involve quantifiable variables that can be tested statistically ( statistical hypothesis ), 11 6) or express a relationship whose interlinks can be verified logically ( logical hypothesis ). 11 We provide examples of simple, complex, directional, non-directional, associative, causal, null, alternative, working, statistical, and logical hypotheses in quantitative research, as well as the definition of quantitative hypothesis-testing research in Table 3 .

Research questions in qualitative research

Unlike research questions in quantitative research, research questions in qualitative research are usually continuously reviewed and reformulated. The central question and associated subquestions are stated more than the hypotheses. 15 The central question broadly explores a complex set of factors surrounding the central phenomenon, aiming to present the varied perspectives of participants. 15

There are varied goals for which qualitative research questions are developed. These questions can function in several ways, such as to 1) identify and describe existing conditions ( contextual research question s); 2) describe a phenomenon ( descriptive research questions ); 3) assess the effectiveness of existing methods, protocols, theories, or procedures ( evaluation research questions ); 4) examine a phenomenon or analyze the reasons or relationships between subjects or phenomena ( explanatory research questions ); or 5) focus on unknown aspects of a particular topic ( exploratory research questions ). 5 In addition, some qualitative research questions provide new ideas for the development of theories and actions ( generative research questions ) or advance specific ideologies of a position ( ideological research questions ). 1 Other qualitative research questions may build on a body of existing literature and become working guidelines ( ethnographic research questions ). Research questions may also be broadly stated without specific reference to the existing literature or a typology of questions ( phenomenological research questions ), may be directed towards generating a theory of some process ( grounded theory questions ), or may address a description of the case and the emerging themes ( qualitative case study questions ). 15 We provide examples of contextual, descriptive, evaluation, explanatory, exploratory, generative, ideological, ethnographic, phenomenological, grounded theory, and qualitative case study research questions in qualitative research in Table 4 , and the definition of qualitative hypothesis-generating research in Table 5 .

Qualitative studies usually pose at least one central research question and several subquestions starting with How or What . These research questions use exploratory verbs such as explore or describe . These also focus on one central phenomenon of interest, and may mention the participants and research site. 15

Hypotheses in qualitative research

Hypotheses in qualitative research are stated in the form of a clear statement concerning the problem to be investigated. Unlike in quantitative research where hypotheses are usually developed to be tested, qualitative research can lead to both hypothesis-testing and hypothesis-generating outcomes. 2 When studies require both quantitative and qualitative research questions, this suggests an integrative process between both research methods wherein a single mixed-methods research question can be developed. 1

FRAMEWORKS FOR DEVELOPING RESEARCH QUESTIONS AND HYPOTHESES

Research questions followed by hypotheses should be developed before the start of the study. 1 , 12 , 14 It is crucial to develop feasible research questions on a topic that is interesting to both the researcher and the scientific community. This can be achieved by a meticulous review of previous and current studies to establish a novel topic. Specific areas are subsequently focused on to generate ethical research questions. The relevance of the research questions is evaluated in terms of clarity of the resulting data, specificity of the methodology, objectivity of the outcome, depth of the research, and impact of the study. 1 , 5 These aspects constitute the FINER criteria (i.e., Feasible, Interesting, Novel, Ethical, and Relevant). 1 Clarity and effectiveness are achieved if research questions meet the FINER criteria. In addition to the FINER criteria, Ratan et al. described focus, complexity, novelty, feasibility, and measurability for evaluating the effectiveness of research questions. 14

The PICOT and PEO frameworks are also used when developing research questions. 1 The following elements are addressed in these frameworks, PICOT: P-population/patients/problem, I-intervention or indicator being studied, C-comparison group, O-outcome of interest, and T-timeframe of the study; PEO: P-population being studied, E-exposure to preexisting conditions, and O-outcome of interest. 1 Research questions are also considered good if these meet the “FINERMAPS” framework: Feasible, Interesting, Novel, Ethical, Relevant, Manageable, Appropriate, Potential value/publishable, and Systematic. 14

As we indicated earlier, research questions and hypotheses that are not carefully formulated result in unethical studies or poor outcomes. To illustrate this, we provide some examples of ambiguous research question and hypotheses that result in unclear and weak research objectives in quantitative research ( Table 6 ) 16 and qualitative research ( Table 7 ) 17 , and how to transform these ambiguous research question(s) and hypothesis(es) into clear and good statements.

CONSTRUCTING RESEARCH QUESTIONS AND HYPOTHESES

To construct effective research questions and hypotheses, it is very important to 1) clarify the background and 2) identify the research problem at the outset of the research, within a specific timeframe. 9 Then, 3) review or conduct preliminary research to collect all available knowledge about the possible research questions by studying theories and previous studies. 18 Afterwards, 4) construct research questions to investigate the research problem. Identify variables to be accessed from the research questions 4 and make operational definitions of constructs from the research problem and questions. Thereafter, 5) construct specific deductive or inductive predictions in the form of hypotheses. 4 Finally, 6) state the study aims . This general flow for constructing effective research questions and hypotheses prior to conducting research is shown in Fig. 1 .

Research questions are used more frequently in qualitative research than objectives or hypotheses. 3 These questions seek to discover, understand, explore or describe experiences by asking “What” or “How.” The questions are open-ended to elicit a description rather than to relate variables or compare groups. The questions are continually reviewed, reformulated, and changed during the qualitative study. 3 Research questions are also used more frequently in survey projects than hypotheses in experiments in quantitative research to compare variables and their relationships.

Hypotheses are constructed based on the variables identified and as an if-then statement, following the template, ‘If a specific action is taken, then a certain outcome is expected.’ At this stage, some ideas regarding expectations from the research to be conducted must be drawn. 18 Then, the variables to be manipulated (independent) and influenced (dependent) are defined. 4 Thereafter, the hypothesis is stated and refined, and reproducible data tailored to the hypothesis are identified, collected, and analyzed. 4 The hypotheses must be testable and specific, 18 and should describe the variables and their relationships, the specific group being studied, and the predicted research outcome. 18 Hypotheses construction involves a testable proposition to be deduced from theory, and independent and dependent variables to be separated and measured separately. 3 Therefore, good hypotheses must be based on good research questions constructed at the start of a study or trial. 12

In summary, research questions are constructed after establishing the background of the study. Hypotheses are then developed based on the research questions. Thus, it is crucial to have excellent research questions to generate superior hypotheses. In turn, these would determine the research objectives and the design of the study, and ultimately, the outcome of the research. 12 Algorithms for building research questions and hypotheses are shown in Fig. 2 for quantitative research and in Fig. 3 for qualitative research.

EXAMPLES OF RESEARCH QUESTIONS FROM PUBLISHED ARTICLES

• EXAMPLE 1. Descriptive research question (quantitative research)
• - Presents research variables to be assessed (distinct phenotypes and subphenotypes)
• “BACKGROUND: Since COVID-19 was identified, its clinical and biological heterogeneity has been recognized. Identifying COVID-19 phenotypes might help guide basic, clinical, and translational research efforts.
• RESEARCH QUESTION: Does the clinical spectrum of patients with COVID-19 contain distinct phenotypes and subphenotypes? ” 19
• EXAMPLE 2. Relationship research question (quantitative research)
• - Shows interactions between dependent variable (static postural control) and independent variable (peripheral visual field loss)
• “Background: Integration of visual, vestibular, and proprioceptive sensations contributes to postural control. People with peripheral visual field loss have serious postural instability. However, the directional specificity of postural stability and sensory reweighting caused by gradual peripheral visual field loss remain unclear.
• Research question: What are the effects of peripheral visual field loss on static postural control ?” 20
• EXAMPLE 3. Comparative research question (quantitative research)
• - Clarifies the difference among groups with an outcome variable (patients enrolled in COMPERA with moderate PH or severe PH in COPD) and another group without the outcome variable (patients with idiopathic pulmonary arterial hypertension (IPAH))
• “BACKGROUND: Pulmonary hypertension (PH) in COPD is a poorly investigated clinical condition.
• RESEARCH QUESTION: Which factors determine the outcome of PH in COPD?
• STUDY DESIGN AND METHODS: We analyzed the characteristics and outcome of patients enrolled in the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) with moderate or severe PH in COPD as defined during the 6th PH World Symposium who received medical therapy for PH and compared them with patients with idiopathic pulmonary arterial hypertension (IPAH) .” 21
• EXAMPLE 4. Exploratory research question (qualitative research)
• - Explores areas that have not been fully investigated (perspectives of families and children who receive care in clinic-based child obesity treatment) to have a deeper understanding of the research problem
• “Problem: Interventions for children with obesity lead to only modest improvements in BMI and long-term outcomes, and data are limited on the perspectives of families of children with obesity in clinic-based treatment. This scoping review seeks to answer the question: What is known about the perspectives of families and children who receive care in clinic-based child obesity treatment? This review aims to explore the scope of perspectives reported by families of children with obesity who have received individualized outpatient clinic-based obesity treatment.” 22
• EXAMPLE 5. Relationship research question (quantitative research)
• - Defines interactions between dependent variable (use of ankle strategies) and independent variable (changes in muscle tone)
• “Background: To maintain an upright standing posture against external disturbances, the human body mainly employs two types of postural control strategies: “ankle strategy” and “hip strategy.” While it has been reported that the magnitude of the disturbance alters the use of postural control strategies, it has not been elucidated how the level of muscle tone, one of the crucial parameters of bodily function, determines the use of each strategy. We have previously confirmed using forward dynamics simulations of human musculoskeletal models that an increased muscle tone promotes the use of ankle strategies. The objective of the present study was to experimentally evaluate a hypothesis: an increased muscle tone promotes the use of ankle strategies. Research question: Do changes in the muscle tone affect the use of ankle strategies ?” 23

EXAMPLES OF HYPOTHESES IN PUBLISHED ARTICLES

• EXAMPLE 1. Working hypothesis (quantitative research)
• - A hypothesis that is initially accepted for further research to produce a feasible theory
• “As fever may have benefit in shortening the duration of viral illness, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response when taken during the early stages of COVID-19 illness .” 24
• “In conclusion, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response . The difference in perceived safety of these agents in COVID-19 illness could be related to the more potent efficacy to reduce fever with ibuprofen compared to acetaminophen. Compelling data on the benefit of fever warrant further research and review to determine when to treat or withhold ibuprofen for early stage fever for COVID-19 and other related viral illnesses .” 24
• EXAMPLE 2. Exploratory hypothesis (qualitative research)
• - Explores particular areas deeper to clarify subjective experience and develop a formal hypothesis potentially testable in a future quantitative approach
• “We hypothesized that when thinking about a past experience of help-seeking, a self distancing prompt would cause increased help-seeking intentions and more favorable help-seeking outcome expectations .” 25
• “Conclusion
• Although a priori hypotheses were not supported, further research is warranted as results indicate the potential for using self-distancing approaches to increasing help-seeking among some people with depressive symptomatology.” 25
• EXAMPLE 3. Hypothesis-generating research to establish a framework for hypothesis testing (qualitative research)
• “We hypothesize that compassionate care is beneficial for patients (better outcomes), healthcare systems and payers (lower costs), and healthcare providers (lower burnout). ” 26
• Compassionomics is the branch of knowledge and scientific study of the effects of compassionate healthcare. Our main hypotheses are that compassionate healthcare is beneficial for (1) patients, by improving clinical outcomes, (2) healthcare systems and payers, by supporting financial sustainability, and (3) HCPs, by lowering burnout and promoting resilience and well-being. The purpose of this paper is to establish a scientific framework for testing the hypotheses above . If these hypotheses are confirmed through rigorous research, compassionomics will belong in the science of evidence-based medicine, with major implications for all healthcare domains.” 26
• EXAMPLE 4. Statistical hypothesis (quantitative research)
• - An assumption is made about the relationship among several population characteristics ( gender differences in sociodemographic and clinical characteristics of adults with ADHD ). Validity is tested by statistical experiment or analysis ( chi-square test, Students t-test, and logistic regression analysis)
• “Our research investigated gender differences in sociodemographic and clinical characteristics of adults with ADHD in a Japanese clinical sample. Due to unique Japanese cultural ideals and expectations of women's behavior that are in opposition to ADHD symptoms, we hypothesized that women with ADHD experience more difficulties and present more dysfunctions than men . We tested the following hypotheses: first, women with ADHD have more comorbidities than men with ADHD; second, women with ADHD experience more social hardships than men, such as having less full-time employment and being more likely to be divorced.” 27
• “Statistical Analysis
• ( text omitted ) Between-gender comparisons were made using the chi-squared test for categorical variables and Students t-test for continuous variables…( text omitted ). A logistic regression analysis was performed for employment status, marital status, and comorbidity to evaluate the independent effects of gender on these dependent variables.” 27

EXAMPLES OF HYPOTHESIS AS WRITTEN IN PUBLISHED ARTICLES IN RELATION TO OTHER PARTS

• EXAMPLE 1. Background, hypotheses, and aims are provided
• “Pregnant women need skilled care during pregnancy and childbirth, but that skilled care is often delayed in some countries …( text omitted ). The focused antenatal care (FANC) model of WHO recommends that nurses provide information or counseling to all pregnant women …( text omitted ). Job aids are visual support materials that provide the right kind of information using graphics and words in a simple and yet effective manner. When nurses are not highly trained or have many work details to attend to, these job aids can serve as a content reminder for the nurses and can be used for educating their patients (Jennings, Yebadokpo, Affo, & Agbogbe, 2010) ( text omitted ). Importantly, additional evidence is needed to confirm how job aids can further improve the quality of ANC counseling by health workers in maternal care …( text omitted )” 28
• “ This has led us to hypothesize that the quality of ANC counseling would be better if supported by job aids. Consequently, a better quality of ANC counseling is expected to produce higher levels of awareness concerning the danger signs of pregnancy and a more favorable impression of the caring behavior of nurses .” 28
• “This study aimed to examine the differences in the responses of pregnant women to a job aid-supported intervention during ANC visit in terms of 1) their understanding of the danger signs of pregnancy and 2) their impression of the caring behaviors of nurses to pregnant women in rural Tanzania.” 28
• EXAMPLE 2. Background, hypotheses, and aims are provided
• “We conducted a two-arm randomized controlled trial (RCT) to evaluate and compare changes in salivary cortisol and oxytocin levels of first-time pregnant women between experimental and control groups. The women in the experimental group touched and held an infant for 30 min (experimental intervention protocol), whereas those in the control group watched a DVD movie of an infant (control intervention protocol). The primary outcome was salivary cortisol level and the secondary outcome was salivary oxytocin level.” 29
• “ We hypothesize that at 30 min after touching and holding an infant, the salivary cortisol level will significantly decrease and the salivary oxytocin level will increase in the experimental group compared with the control group .” 29
• EXAMPLE 3. Background, aim, and hypothesis are provided
• “In countries where the maternal mortality ratio remains high, antenatal education to increase Birth Preparedness and Complication Readiness (BPCR) is considered one of the top priorities [1]. BPCR includes birth plans during the antenatal period, such as the birthplace, birth attendant, transportation, health facility for complications, expenses, and birth materials, as well as family coordination to achieve such birth plans. In Tanzania, although increasing, only about half of all pregnant women attend an antenatal clinic more than four times [4]. Moreover, the information provided during antenatal care (ANC) is insufficient. In the resource-poor settings, antenatal group education is a potential approach because of the limited time for individual counseling at antenatal clinics.” 30
• “This study aimed to evaluate an antenatal group education program among pregnant women and their families with respect to birth-preparedness and maternal and infant outcomes in rural villages of Tanzania.” 30
• “ The study hypothesis was if Tanzanian pregnant women and their families received a family-oriented antenatal group education, they would (1) have a higher level of BPCR, (2) attend antenatal clinic four or more times, (3) give birth in a health facility, (4) have less complications of women at birth, and (5) have less complications and deaths of infants than those who did not receive the education .” 30

Research questions and hypotheses are crucial components to any type of research, whether quantitative or qualitative. These questions should be developed at the very beginning of the study. Excellent research questions lead to superior hypotheses, which, like a compass, set the direction of research, and can often determine the successful conduct of the study. Many research studies have floundered because the development of research questions and subsequent hypotheses was not given the thought and meticulous attention needed. The development of research questions and hypotheses is an iterative process based on extensive knowledge of the literature and insightful grasp of the knowledge gap. Focused, concise, and specific research questions provide a strong foundation for constructing hypotheses which serve as formal predictions about the research outcomes. Research questions and hypotheses are crucial elements of research that should not be overlooked. They should be carefully thought of and constructed when planning research. This avoids unethical studies and poor outcomes by defining well-founded objectives that determine the design, course, and outcome of the study.

What is evaluation research?

Evaluation research, also known as program evaluation, refers to research purpose instead of a specific method. Evaluation research is the systematic assessment of the worth or merit of time, money, effort and resources spent in order to achieve a goal.

Evaluation research is closely related to but slightly different from more conventional social research . It uses many of the same methods used in traditional social research, but because it takes place within an organizational context, it requires team skills, interpersonal skills, management skills, political smartness, and other research skills that social research does not need much. Evaluation research also requires one to keep in mind the interests of the stakeholders.

Evaluation research is a type of applied research, and so it is intended to have some real-world effect.  Many methods like surveys and experiments can be used to do evaluation research. The process of evaluation research consisting of data analysis and reporting is a rigorous, systematic process that involves collecting data about organizations, processes, projects, services, and/or resources. Evaluation research enhances knowledge and decision-making, and leads to practical applications.

LEARN ABOUT: Action Research

Why do evaluation research?

The common goal of most evaluations is to extract meaningful information from the audience and provide valuable insights to evaluators such as sponsors, donors, client-groups, administrators, staff, and other relevant constituencies. Most often, feedback is perceived value as useful if it helps in decision-making. However, evaluation research does not always create an impact that can be applied anywhere else, sometimes they fail to influence short-term decisions. It is also equally true that initially, it might seem to not have any influence, but can have a delayed impact when the situation is more favorable. In spite of this, there is a general agreement that the major goal of evaluation research should be to improve decision-making through the systematic utilization of measurable feedback.

Below are some of the benefits of evaluation research

• Gain insights about a project or program and its operations

Evaluation Research lets you understand what works and what doesn’t, where we were, where we are and where we are headed towards. You can find out the areas of improvement and identify strengths. So, it will help you to figure out what do you need to focus more on and if there are any threats to your business. You can also find out if there are currently hidden sectors in the market that are yet untapped.

• Improve practice

It is essential to gauge your past performance and understand what went wrong in order to deliver better services to your customers. Unless it is a two-way communication, there is no way to improve on what you have to offer. Evaluation research gives an opportunity to your employees and customers to express how they feel and if there’s anything they would like to change. It also lets you modify or adopt a practice such that it increases the chances of success.

• Assess the effects

After evaluating the efforts, you can see how well you are meeting objectives and targets. Evaluations let you measure if the intended benefits are really reaching the targeted audience and if yes, then how effectively.

• Build capacity

Evaluations help you to analyze the demand pattern and predict if you will need more funds, upgrade skills and improve the efficiency of operations. It lets you find the gaps in the production to delivery chain and possible ways to fill them.

Methods of evaluation research

All market research methods involve collecting and analyzing the data, making decisions about the validity of the information and deriving relevant inferences from it. Evaluation research comprises of planning, conducting and analyzing the results which include the use of data collection techniques and applying statistical methods.

Some of the evaluation methods which are quite popular are input measurement, output or performance measurement, impact or outcomes assessment, quality assessment, process evaluation, benchmarking, standards, cost analysis, organizational effectiveness, program evaluation methods, and LIS-centered methods. There are also a few types of evaluations that do not always result in a meaningful assessment such as descriptive studies, formative evaluations, and implementation analysis. Evaluation research is more about information-processing and feedback functions of evaluation.

These methods can be broadly classified as quantitative and qualitative methods.

The outcome of the quantitative research methods is an answer to the questions below and is used to measure anything tangible.

• Who was involved?
• What were the outcomes?
• What was the price?

The best way to collect quantitative data is through surveys , questionnaires , and polls . You can also create pre-tests and post-tests, review existing documents and databases or gather clinical data.

Surveys are used to gather opinions, feedback or ideas of your employees or customers and consist of various question types . They can be conducted by a person face-to-face or by telephone, by mail, or online. Online surveys do not require the intervention of any human and are far more efficient and practical. You can see the survey results on dashboard of research tools and dig deeper using filter criteria based on various factors such as age, gender, location, etc. You can also keep survey logic such as branching, quotas, chain survey, looping, etc in the survey questions and reduce the time to both create and respond to the donor survey . You can also generate a number of reports that involve statistical formulae and present data that can be readily absorbed in the meetings.

Quantitative data measure the depth and breadth of an initiative, for instance, the number of people who participated in the non-profit event, the number of people who enrolled for a new course at the university. Quantitative data collected before and after a program can show its results and impact.

The accuracy of quantitative data to be used for evaluation research depends on how well the sample represents the population, the ease of analysis, and their consistency. Quantitative methods can fail if the questions are not framed correctly and not distributed to the right audience. Also, quantitative data do not provide an understanding of the context and may not be apt for complex issues.

Qualitative research methods are used where quantitative methods cannot solve the research problem , i.e. they are used to measure intangible values. They answer questions such as

• What is the value added?
• How satisfied are you with our service?
• How likely are you to recommend us to your friends?
• What will improve your experience?

LEARN ABOUT: Qualitative Interview

Qualitative data is collected through observation, interviews, case studies, and focus groups. The steps for creating a qualitative study involve examining, comparing and contrasting, and understanding patterns. Analysts conclude after identification of themes, clustering similar data, and finally reducing to points that make sense.

Observations may help explain behaviors as well as the social context that is generally not discovered by quantitative methods. Observations of behavior and body language can be done by watching a participant, recording audio or video. Structured interviews can be conducted with people alone or in a group under controlled conditions, or they may be asked open-ended qualitative research questions . Qualitative research methods are also used to understand a person’s perceptions and motivations.

LEARN ABOUT:  Social Communication Questionnaire

The strength of this method is that group discussion can provide ideas and stimulate memories with topics cascading as discussion occurs. The accuracy of qualitative data depends on how well contextual data explains complex issues and complements quantitative data. It helps get the answer of “why” and “how”, after getting an answer to “what”. The limitations of qualitative data for evaluation research are that they are subjective, time-consuming, costly and difficult to analyze and interpret.

Learn more: Qualitative Market Research: The Complete Guide

Survey software can be used for both the evaluation research methods. You can use above sample questions for evaluation research and send a survey in minutes using research software. Using a tool for research simplifies the process right from creating a survey, importing contacts, distributing the survey and generating reports that aid in research.

Examples of evaluation research

Evaluation research questions lay the foundation of a successful evaluation. They define the topics that will be evaluated. Keeping evaluation questions ready not only saves time and money, but also makes it easier to decide what data to collect, how to analyze it, and how to report it.

Evaluation research questions must be developed and agreed on in the planning stage, however, ready-made research templates can also be used.

Process evaluation research question examples:

• How often do you use our product in a day?
• Were approvals taken from all stakeholders?
• Can you report the issue from the system?
• Can you submit the feedback from the system?
• Was each task done as per the standard operating procedure?
• What were the barriers to the implementation of each task?
• Were any improvement areas discovered?

Outcome evaluation research question examples:

• How satisfied are you with our product?
• Did the program produce intended outcomes?
• What were the unintended outcomes?
• Has the program increased the knowledge of participants?
• Were the participants of the program employable before the course started?
• Do participants of the program have the skills to find a job after the course ended?
• Is the knowledge of participants better compared to those who did not participate in the program?

7 Steps for How to Write an Evaluation Essay (Example & Template)

In this ultimate guide, I will explain to you exactly how to write an evaluation essay.

1. What is an Evaluation Essay?

An evaluation essay should provide a critical analysis of something.

You’re literally ‘evaluating’ the thing you’re looking up.

Here’s a couple of quick definitions of what we mean by ‘evaluate’:

• Merriam-Webster defines evaluation as: “to determine the significance, worth, or condition of usually by careful appraisal and study”
• Collins Dictionary says: “If you evaluate something or someone, you consider them in order to make a judgment about them, for example about how good or bad they are.”

Here’s some synonyms for ‘evaluate’:

So, we could say that an evaluation essay should carefully examine the ‘thing’ and provide an overall judgement of it.

Here’s some common things you may be asked to write an evaluation essay on:

This is by no means an exhaustive list. Really, you can evaluate just about anything!

2. How to write an Evaluation Essay

There are two secrets to writing a strong evaluation essay. The first is to aim for objective analysis before forming an opinion. The second is to use an evaluation criteria.

Aim to Appear Objective before giving an Evaluation Argument

Your evaluation will eventually need an argument.

The evaluation argument will show your reader what you have decided is the final value of the ‘thing’ you’re evaluating.

But in order to convince your reader that your evaluative argument is sound, you need to do some leg work.

The aim will be to show that you have provided a balanced and fair assessment before coming to your conclusion.

In order to appear balanced you should:

• Discuss both the pros and cons of the thing
• Discuss both the strengths and weaknesses of the thing
• Look at the thing from multiple different perspectives
• Be both positive and critical. Don’t make it look like you’re biased towards one perspective.

In other words, give every perspective a fair hearing.

You don’t want to sound like a propagandist. You want to be seen as a fair and balanced adjudicator.

Use an Evaluation Criteria

One way to appear balanced is to use an evaluation criteria.

An evaluation criteria helps to show that you have assessed the ‘thing’ based on an objective measure.

Here’s some examples of evaluation criteria:

• Strength under pressure
• Longevity (ability to survive for a long time)
• Ease of use
• Ability to get the job done
• Friendliness
• Punctuality
• Ability to predict my needs
• Calmness under pressure
• Attentiveness

A Bed and Breakfast

• Breakfast options
• Taste of food
• Comfort of bed
• Local attractions
• Service from owner
• Cleanliness

We can use evaluation criteria to frame out ability to conduct the analysis fairly.

This is especially true for if you have to evaluate multiple different ‘things’. For example, if you’re evaluating three novels, you want to be able to show that you applied the same ‘test’ on all three books!

This will show that you gave each ‘thing’ a fair chance and looked at the same elements for each.

3. How to come up with an Evaluation Argument

After you have:

• Looked at both good and bad elements of the ‘thing’, and
• Used an evaluation criteria

You’ll then need to develop an evaluative argument. This argument shows your own overall perspective on the ‘thing’.

Remember, you will need to show your final evaluative argument is backed by objective analysis. You need to do it in order!

Analyze first. Evaluate second.

Here’s an example.

Let’s say you’re evaluating the quality of a meal.

You might say:

• A strength of the meal was its presentation. It was well presented and looked enticing to eat.
• A weakness of the meal was that it was overcooked. This decreased its flavor.
• The meal was given a low rating on ‘cost’ because it was more expensive than the other comparative meals on the menu.
• The meal was given a high rating on ‘creativity’. It was a meal that involved a thoughtful and inventive mix of ingredients.

Now that you’ve looked at some pros and cons and measured the meal based on a few criteria points (like cost and creativity), you’ll be able to come up with a final argument:

• Overall, the meal was good enough for a middle-tier restaurant but would not be considered a high-class meal. There is a lot of room for improvement if the chef wants to win any local cooking awards.

Evaluative terms that you might want to use for this final evaluation argument might include:

• All things considered
• With all key points in mind

4. Evaluation Essay Outline (with Examples)

Okay, so now you know what to do, let’s have a go at creating an outline for your evaluation essay!

Here’s what I recommend:

4.1 How to Write your Introduction

In the introduction, feel free to use my 5-Step INTRO method . It’ll be an introduction just like any other essay introduction .

And yes, feel free to explain what the final evaluation will be.

So, here it is laid out nice and simple.

Write one sentence for each point to make a 5-sentence introduction:

• Interest: Make a statement about the ‘thing’ you’re evaluating that you think will be of interest to the reader. Make it a catchy, engaging point that draws the reader in!
• Notify: Notify the reader of any background info on the thing you’re evaluating. This is your chance to show your depth of knowledge. What is a historical fact about the ‘thing’?
• Translate: Re-state the essay question. For an evaluative essay, you can re-state it something like: “This essay evaluates the book/ product/ article/ etc. by looking at its strengths and weaknesses and compares it against a marking criteria”.
• Report: Say what your final evaluation will be. For example you can say “While there are some weaknesses in this book, overall this evaluative essay will show that it helps progress knowledge about Dinosaurs.”
• Outline: Simply give a clear overview of what will be discussed. For example, you can say: “Firstly, the essay will evaluate the product based on an objective criteria. This criteria will include its value for money, fit for purpose and ease of use. Next, the essay will show the main strengths and weaknesses of the product. Lastly, the essay will provide a final evaluative statement about the product’s overall value and worth.”

4.2 Example Introduction

This example introduction is for the essay question: Write an Evaluation Essay on Facebook’s Impact on Society.

“Facebook is the third most visited website in the world. It was founded in 2004 by Mark Zuckerberg in his college dorm. This essay evaluates the impact of Facebook on society and makes an objective judgement on its value. The essay will argue that Facebook has changed the world both for the better and worse. Firstly, it will give an overview of what Facebook is and its history. Then, it will examine Facebook on the criteria of: impact on social interactions, impact on the media landscape, and impact on politics.”

You’ll notice that each sentence in this introduction follows my 5-Step INTRO formula to create a clear, coherent 5-Step introduction.

4.3 How to Write your Body Paragraphs

The first body paragraph should give an overview of the ‘thing’ being evaluated.

Then, you should evaluate the pros and cons of the ‘thing’ being evaluated based upon the criteria you have developed for evaluating it.

Let’s take a look below.

4.4 First Body Paragraph: Overview of your Subject

This first paragraph should provide objective overview of your subject’s properties and history. You should not be doing any evaluating just yet.

The goal for this first paragraph is to ensure your reader knows what it is you’re evaluating. Secondarily, it should show your marker that you have developed some good knowledge about it.

If you need to use more than one paragraph to give an overview of the subject, that’s fine.

Similarly, if your essay word length needs to be quite long, feel free to spend several paragraphs exploring the subject’s background and objective details to show off your depth of knowledge for the marker.

4.5 First Body Paragraph Example

Sticking with the essay question: Write an Evaluation Essay on Facebook’s Impact on Society , this might be your paragraph:

“Facebook has been one of the most successful websites of all time. It is the website that dominated the ‘Web 2.0’ revolution, which was characterized by user two-way interaction with the web. Facebook allowed users to create their own personal profiles and invite their friends to follow along. Since 2004, Facebook has attracted more than one billion people to create profiles in order to share their opinions and keep in touch with their friends.”

Notice here that I haven’t yet made any evaluations of Facebook’s merits?

This first paragraph (or, if need be, several of them) should be all about showing the reader exactly what your subject is – no more, no less.

4.6 Evaluation Paragraphs: Second, Third, Forth and Fifth Body Paragraphs

Once you’re confident your reader will know what the subject that you’re evaluating is, you’ll need to move on to the actual evaluation.

For this step, you’ll need to dig up that evaluation criteria we talked about in Point 2.

For example, let’s say you’re evaluating a President of the United States.

Your evaluation criteria might be:

• Impact on world history
• Ability to pass legislation
• Popularity with voters
• Morals and ethics
• Ability to change lives for the better

Really, you could make up any evaluation criteria you want!

Once you’ve made up the evaluation criteria, you’ve got your evaluation paragraph ideas!

Simply turn each point in your evaluation criteria into a full paragraph.

How do you do this?

Well, start with a topic sentence.

For the criteria point ‘Impact on world history’ you can say something like: “Barack Obama’s impact on world history is mixed.”

This topic sentence will show that you’ll evaluate both pros and cons of Obama’s impact on world history in the paragraph.

Then, follow it up with explanations.

“While Obama campaigned to withdraw troops from Iraq and Afghanistan, he was unable to completely achieve this objective. This is an obvious negative for his impact on the world. However, as the first black man to lead the most powerful nation on earth, he will forever be remembered as a living milestone for civil rights and progress.”

Keep going, turning each evaluation criteria into a full paragraph.

4.7 Evaluation Paragraph Example

Let’s go back to our essay question: Write an Evaluation Essay on Facebook’s Impact on Society .

I’ve decided to use the evaluation criteria below:

• impact on social interactions;
• impact on the media landscape;
• impact on politics

Naturally, I’m going to write one paragraph for each point.

If you’re expected to write a longer piece, you could write two paragraphs on each point (one for pros and one for cons).

Here’s what my first evaluation paragraph might look like:

“Facebook has had a profound impact on social interactions. It has helped people to stay in touch with one another from long distances and after they have left school and college. This is obviously a great positive. However, it can also be seen as having a negative impact. For example, people may be less likely to interact face-to-face because they are ‘hanging out’ online instead. This can have negative impact on genuine one-to-one relationships.”

You might notice that this paragraph has a topic sentence, explanations and examples. It follows my perfect paragraph formula which you’re more than welcome to check out!

4.8 How to write your Conclusion

To conclude, you’ll need to come up with one final evaluative argument.

This evaluation argument provides an overall assessment. You can start with “Overall, Facebook has been…” and continue by saying that (all things considered) he was a good or bad president!

Remember, you can only come up with an overall evaluation after you’ve looked at the subject’s pros and cons based upon your evaluation criteria.

In the example below, I’m going to use my 5 C’s conclusion paragraph method . This will make sure my conclusion covers all the things a good conclusion should cover!

Like the INTRO method, the 5 C’s conclusion method should have one sentence for each point to create a 5 sentence conclusion paragraph.

The 5 C’s conclusion method is:

• Close the loop: Return to a statement you made in the introduction.
• Conclude: Show what your final position is.
• Clarify: Clarify how your final position is relevant to the Essay Question.
• Concern: Explain who should be concerned by your findings.
• Consequences: End by noting in one final, engaging sentence why this topic is of such importance. The ‘concern’ and ‘consequences’ sentences can be combined

4.9 Concluding Argument Example Paragraph

Here’s a possible concluding argument for our essay question: Write an Evaluation Essay on Facebook’s Impact on Society .

“The introduction of this essay highlighted that Facebook has had a profound impact on society. This evaluation essay has shown that this impact has been both positive and negative. Thus, it is too soon to say whether Facebook has been an overall positive or negative for society. However, people should pay close attention to this issue because it is possible that Facebook is contributing to the undermining of truth in media and positive interpersonal relationships.”

Note here that I’ve followed the 5 C’s conclusion method for my concluding evaluative argument paragraph.

The trick for getting good marks in an evaluation essay is to show you have looked at both the pros and cons before making a final evaluation analysis statement.

You don’t want to look biased.

That’s why it’s a good idea to use an objective evaluation criteria, and to be generous in looking at both positives and negatives of your subject.

2 thoughts on “7 Steps for How to Write an Evaluation Essay (Example & Template)”

What an amazing article. I am returning to studying after several years and was struggling with how to present an evaluative essay. This article has simplified the process and provided me with the confidence to tackle my subject (theoretical approaches to development and management of teams).

I just wanted to ask whether the evaluation criteria has to be supported by evidence or can it just be a list of criteria that you think of yourself to objectively measure?

Many many thanks for writing this!

Usually we would want to see evidence, but ask your teacher for what they’re looking for as they may allow you, depending on the situation.

The methods section describes actions taken to investigate a research problem and the rationale for the application of specific procedures or techniques used to identify, select, process, and analyze information applied to understanding the problem, thereby, allowing the reader to critically evaluate a study’s overall validity and reliability. The methodology section of a research paper answers two main questions: How was the data collected or generated? And, how was it analyzed? The writing should be direct and precise and always written in the past tense.

Kallet, Richard H. "How to Write the Methods Section of a Research Paper." Respiratory Care 49 (October 2004): 1229-1232.

Importance of a Good Methodology Section

You must explain how you obtained and analyzed your results for the following reasons:

• Readers need to know how the data was obtained because the method you chose affects the results and, by extension, how you interpreted their significance in the discussion section of your paper.
• Methodology is crucial for any branch of scholarship because an unreliable method produces unreliable results and, as a consequence, undermines the value of your analysis of the findings.
• In most cases, there are a variety of different methods you can choose to investigate a research problem. The methodology section of your paper should clearly articulate the reasons why you have chosen a particular procedure or technique.
• The reader wants to know that the data was collected or generated in a way that is consistent with accepted practice in the field of study. For example, if you are using a multiple choice questionnaire, readers need to know that it offered your respondents a reasonable range of answers to choose from.
• The method must be appropriate to fulfilling the overall aims of the study. For example, you need to ensure that you have a large enough sample size to be able to generalize and make recommendations based upon the findings.
• The methodology should discuss the problems that were anticipated and the steps you took to prevent them from occurring. For any problems that do arise, you must describe the ways in which they were minimized or why these problems do not impact in any meaningful way your interpretation of the findings.
• In the social and behavioral sciences, it is important to always provide sufficient information to allow other researchers to adopt or replicate your methodology. This information is particularly important when a new method has been developed or an innovative use of an existing method is utilized.

Structure and Writing Style

I.  Groups of Research Methods

There are two main groups of research methods in the social sciences:

• The e mpirical-analytical group approaches the study of social sciences in a similar manner that researchers study the natural sciences . This type of research focuses on objective knowledge, research questions that can be answered yes or no, and operational definitions of variables to be measured. The empirical-analytical group employs deductive reasoning that uses existing theory as a foundation for formulating hypotheses that need to be tested. This approach is focused on explanation.
• The i nterpretative group of methods is focused on understanding phenomenon in a comprehensive, holistic way . Interpretive methods focus on analytically disclosing the meaning-making practices of human subjects [the why, how, or by what means people do what they do], while showing how those practices arrange so that it can be used to generate observable outcomes. Interpretive methods allow you to recognize your connection to the phenomena under investigation. However, the interpretative group requires careful examination of variables because it focuses more on subjective knowledge.

II.  Content

The introduction to your methodology section should begin by restating the research problem and underlying assumptions underpinning your study. This is followed by situating the methods you used to gather, analyze, and process information within the overall “tradition” of your field of study and within the particular research design you have chosen to study the problem. If the method you choose lies outside of the tradition of your field [i.e., your review of the literature demonstrates that the method is not commonly used], provide a justification for how your choice of methods specifically addresses the research problem in ways that have not been utilized in prior studies.

The remainder of your methodology section should describe the following:

• Decisions made in selecting the data you have analyzed or, in the case of qualitative research, the subjects and research setting you have examined,
• Tools and methods used to identify and collect information, and how you identified relevant variables,
• The ways in which you processed the data and the procedures you used to analyze that data, and
• The specific research tools or strategies that you utilized to study the underlying hypothesis and research questions.

In addition, an effectively written methodology section should:

• Introduce the overall methodological approach for investigating your research problem . Is your study qualitative or quantitative or a combination of both (mixed method)? Are you going to take a special approach, such as action research, or a more neutral stance?
• Indicate how the approach fits the overall research design . Your methods for gathering data should have a clear connection to your research problem. In other words, make sure that your methods will actually address the problem. One of the most common deficiencies found in research papers is that the proposed methodology is not suitable to achieving the stated objective of your paper.
• Describe the specific methods of data collection you are going to use , such as, surveys, interviews, questionnaires, observation, archival research. If you are analyzing existing data, such as a data set or archival documents, describe how it was originally created or gathered and by whom. Also be sure to explain how older data is still relevant to investigating the current research problem.
• Explain how you intend to analyze your results . Will you use statistical analysis? Will you use specific theoretical perspectives to help you analyze a text or explain observed behaviors? Describe how you plan to obtain an accurate assessment of relationships, patterns, trends, distributions, and possible contradictions found in the data.
• Provide background and a rationale for methodologies that are unfamiliar for your readers . Very often in the social sciences, research problems and the methods for investigating them require more explanation/rationale than widely accepted rules governing the natural and physical sciences. Be clear and concise in your explanation.
• Provide a justification for subject selection and sampling procedure . For instance, if you propose to conduct interviews, how do you intend to select the sample population? If you are analyzing texts, which texts have you chosen, and why? If you are using statistics, why is this set of data being used? If other data sources exist, explain why the data you chose is most appropriate to addressing the research problem.
• Provide a justification for case study selection . A common method of analyzing research problems in the social sciences is to analyze specific cases. These can be a person, place, event, phenomenon, or other type of subject of analysis that are either examined as a singular topic of in-depth investigation or multiple topics of investigation studied for the purpose of comparing or contrasting findings. In either method, you should explain why a case or cases were chosen and how they specifically relate to the research problem.
• Describe potential limitations . Are there any practical limitations that could affect your data collection? How will you attempt to control for potential confounding variables and errors? If your methodology may lead to problems you can anticipate, state this openly and show why pursuing this methodology outweighs the risk of these problems cropping up.

NOTE:   Once you have written all of the elements of the methods section, subsequent revisions should focus on how to present those elements as clearly and as logically as possibly. The description of how you prepared to study the research problem, how you gathered the data, and the protocol for analyzing the data should be organized chronologically. For clarity, when a large amount of detail must be presented, information should be presented in sub-sections according to topic. If necessary, consider using appendices for raw data.

ANOTHER NOTE: If you are conducting a qualitative analysis of a research problem , the methodology section generally requires a more elaborate description of the methods used as well as an explanation of the processes applied to gathering and analyzing of data than is generally required for studies using quantitative methods. Because you are the primary instrument for generating the data [e.g., through interviews or observations], the process for collecting that data has a significantly greater impact on producing the findings. Therefore, qualitative research requires a more detailed description of the methods used.

YET ANOTHER NOTE:   If your study involves interviews, observations, or other qualitative techniques involving human subjects , you may be required to obtain approval from the university's Office for the Protection of Research Subjects before beginning your research. This is not a common procedure for most undergraduate level student research assignments. However, i f your professor states you need approval, you must include a statement in your methods section that you received official endorsement and adequate informed consent from the office and that there was a clear assessment and minimization of risks to participants and to the university. This statement informs the reader that your study was conducted in an ethical and responsible manner. In some cases, the approval notice is included as an appendix to your paper.

III.  Problems to Avoid

Irrelevant Detail The methodology section of your paper should be thorough but concise. Do not provide any background information that does not directly help the reader understand why a particular method was chosen, how the data was gathered or obtained, and how the data was analyzed in relation to the research problem [note: analyzed, not interpreted! Save how you interpreted the findings for the discussion section]. With this in mind, the page length of your methods section will generally be less than any other section of your paper except the conclusion.

Unnecessary Explanation of Basic Procedures Remember that you are not writing a how-to guide about a particular method. You should make the assumption that readers possess a basic understanding of how to investigate the research problem on their own and, therefore, you do not have to go into great detail about specific methodological procedures. The focus should be on how you applied a method , not on the mechanics of doing a method. An exception to this rule is if you select an unconventional methodological approach; if this is the case, be sure to explain why this approach was chosen and how it enhances the overall process of discovery.

Problem Blindness It is almost a given that you will encounter problems when collecting or generating your data, or, gaps will exist in existing data or archival materials. Do not ignore these problems or pretend they did not occur. Often, documenting how you overcame obstacles can form an interesting part of the methodology. It demonstrates to the reader that you can provide a cogent rationale for the decisions you made to minimize the impact of any problems that arose.

Literature Review Just as the literature review section of your paper provides an overview of sources you have examined while researching a particular topic, the methodology section should cite any sources that informed your choice and application of a particular method [i.e., the choice of a survey should include any citations to the works you used to help construct the survey].

It’s More than Sources of Information! A description of a research study's method should not be confused with a description of the sources of information. Such a list of sources is useful in and of itself, especially if it is accompanied by an explanation about the selection and use of the sources. The description of the project's methodology complements a list of sources in that it sets forth the organization and interpretation of information emanating from those sources.

Writing Tip

Statistical Designs and Tests? Do Not Fear Them!

Don't avoid using a quantitative approach to analyzing your research problem just because you fear the idea of applying statistical designs and tests. A qualitative approach, such as conducting interviews or content analysis of archival texts, can yield exciting new insights about a research problem, but it should not be undertaken simply because you have a disdain for running a simple regression. A well designed quantitative research study can often be accomplished in very clear and direct ways, whereas, a similar study of a qualitative nature usually requires considerable time to analyze large volumes of data and a tremendous burden to create new paths for analysis where previously no path associated with your research problem had existed.

Another Writing Tip

Knowing the Relationship Between Theories and Methods

There can be multiple meaning associated with the term "theories" and the term "methods" in social sciences research. A helpful way to delineate between them is to understand "theories" as representing different ways of characterizing the social world when you research it and "methods" as representing different ways of generating and analyzing data about that social world. Framed in this way, all empirical social sciences research involves theories and methods, whether they are stated explicitly or not. However, while theories and methods are often related, it is important that, as a researcher, you deliberately separate them in order to avoid your theories playing a disproportionate role in shaping what outcomes your chosen methods produce.

Introspectively engage in an ongoing dialectic between the application of theories and methods to help enable you to use the outcomes from your methods to interrogate and develop new theories, or ways of framing conceptually the research problem. This is how scholarship grows and branches out into new intellectual territory.

Yet Another Writing Tip

Methods and the Methodology

Do not confuse the terms "methods" and "methodology." As Schneider notes, a method refers to the technical steps taken to do research . Descriptions of methods usually include defining and stating why you have chosen specific techniques to investigate a research problem, followed by an outline of the procedures you used to systematically select, gather, and process the data [remember to always save the interpretation of data for the discussion section of your paper].

The methodology refers to a discussion of the underlying reasoning why particular methods were used . This discussion includes describing the theoretical concepts that inform the choice of methods to be applied, placing the choice of methods within the more general nature of academic work, and reviewing its relevance to examining the research problem. The methodology section also includes a thorough review of the methods other scholars have used to study the topic.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.
