What Does The Discussion Section Of A Research Paper Include

This section describes an organizational structure commonly used to report experimental research in many scientific disciplines, the IMRAD format: Introduction, Methods, Results, And Discussion.

Although the main headings are standard for many scientific fields, details may vary; check with your instructor, or, if submitting an article to a journal, refer to the instructions to authors.

Discussion Section

The table below offers some questions effective discussion sections in scientific reports address.

What do your observations mean?

  • Summarize the most important findings at the beginning.

What conclusions can you draw?

For each major result:

  • Describe the patterns, principles, relationships your results show.
  • Explain how your results relate to expectations and to literature cited in your Introduction. Do they agree, contradict, or are they exceptions to the rule?
  • Explain plausibly any agreements, contradictions, or exceptions.
  • Describe what additional research might resolve contradictions or explain exceptions.

How do your results fit into a broader context?

  • Suggest the theoretical implications of your results.
  • Suggest practical applications of your results?
  • Extend your findings to other situations or other species.
  • Give the big picture: do your findings help us understand a broader topic?

Additional tips:

  1. Move from specific to general: your finding(s) --> literature, theory, practice.
  2. Don't ignore or bury the major issue. Did the study achieve the goal (resolve the problem, answer the question, support the hypothesis) presented in the Introduction?
  3. Make explanations complete.
    • Give evidence for each conclusion.
    • Discuss possible reasons for expected and unexpected findings.

What to avoid:

  1. Don't overgeneralize.
  2. Don't ignore deviations in your data.
  3. Avoid speculation that cannot be tested in the foreseeable future.

 

I.  General Rules

These are the general rules you should adopt when composing your discussion of the results:

  • Do not be verbose or repetitive.
  • Be concise and make your points clearly.
  • Avoid using jargon.
  • Follow a logical stream of thought.
  • Use the present verb tense, especially for established facts; however, refer to specific works and references in the past tense.
  • If needed, use subheadings to help organize your presentation or to group your interpretations into themes.

II.  The Content

The content of the discussion section of your paper most often includes:

  1. Explanation of results: comment on whether or not the results were expected and present explanations for the results; go into greater depth when explaining findings that were unexpected or especially profound. If appropriate, note any unusual or unanticipated patterns or trends that emerged from your results and explain their meaning.
  2. References to previous research: compare your results with the findings from other studies, or use the studies to support a claim. This can include re-visiting key sources already cited in your literature review section, or, save them to cite later in the discussion section if they are more important to compare with your results than being part of the general research you cited to provide context and background information.
  3. Deduction: a claim for how the results can be applied more generally. For example, describing lessons learned, proposing recommendations that can help improve a situation, or recommending best practices.
  4. Hypothesis: a more general claim or possible conclusion arising from the results [which may be proved or disproved in subsequent research].

III. Organization and Structure

Keep the following sequential points in mind as you organize and write the discussion section of your paper:

  1. Think of your discussion as an inverted pyramid. Organize the discussion from the general to the specific, linking your findings to the literature, then to theory, then to practice [if appropriate].
  2. Use the same key terms, mode of narration, and verb tense [present] that you used when when describing the research problem in the introduction.
  3. Begin by briefly re-stating the research problem you were investigating and answer all of the research questions underpinning the problem that you posed in the introduction.
  4. Describe the patterns, principles, and relationships shown by each major findings and place them in proper perspective. The sequencing of providing this information is important; first state the answer, then the relevant results, then cite the work of others. If appropriate, refer the reader to a figure or table to help enhance the interpretation of the data. The order of interpreting each major finding should be in the same order as they were described in your results section.
  5. A good discussion section includes analysis of any unexpected findings. This paragraph should begin with a description of the unexpected finding, followed by a brief interpretation as to why you believe it appeared and, if necessary, its possible significance in relation to the overall study. If more than one unexpected finding emerged during the study, describe each them in the order they appeared as you gathered the data.
  6. Before concluding the discussion, identify potential limitations and weaknesses. Comment on their relative importance in relation to your overall interpretation of the results and, if necessary, note how they may affect the validity of the findings. Avoid using an apologetic tone; however, be honest and self-critical.
  7. The discussion section should end with a concise summary of the principal implications of the findings regardless of statistical significance. Give a brief explanation about why you believe the findings and conclusions of your study are important and how they support broader knowledge or understanding of the research problem. This can be followed by any recommendations for further research. However, do not offer recommendations which could have been easily addressed within the study. This demonstrates to the reader you have inadequately examined and interpreted the data.


IV.  Overall Objectives

The objectives of your discussion section should include the following:

I.  Reiterate the Research Problem/State the Major Findings

Briefly reiterate for your readers the research problem or problems you are investigating and the methods you used to investigate them, then move quickly to describe the major findings of the study. You should write a direct, declarative, and succinct proclamation of the study results.

II.  Explain the Meaning of the Findings and Why They are Important

No one has thought as long and hard about your study as you have. Systematically explain the meaning of the findings and why you believe they are important. After reading the discussion section, you want the reader to think about the results [“why hadn’t I thought of that?”]. You don’t want to force the reader to go through the paper multiple times to figure out what it all means. Begin this part of the section by repeating what you consider to be your most important finding first.

III.  Relate the Findings to Similar Studies

No study is so novel or possesses such a restricted focus that it has absolutely no relation to other previously published research. The discussion section should relate your study findings to those of other studies, particularly if questions raised by previous studies served as the motivation for your study, the findings of other studies support your findings [which strengthens the importance of your study results], and/or they point out how your study differs from other similar studies.

IV.  Consider Alternative Explanations of the Findings

It is important to remember that the purpose of research is to discover and not to prove. When writing the discussion section, you should carefully consider all possible explanations for the study results, rather than just those that fit your prior assumptions or biases.

V.  Acknowledge the Study’s Limitations

It is far better for you to identify and acknowledge your study’s limitations than to have them pointed out by your professor! Describe the generalizability of your results to other situations, if applicable to the method chosen, then describe in detail problems you encountered in the method(s) you used to gather information. Note any unanswered questions or issues your study did not address, and....

VI.  Make Suggestions for Further Research

Although your study may offer important insights about the research problem, other questions related to the problem likely remain unanswered. Moreover, some unanswered questions may have become more focused because of your study. You should make suggestions for further research in the discussion section.

NOTE: Besides the literature review section, the preponderance of references to sources in your research paper are usually found in the discussion section. A few historical references may be helpful for perspective but most of the references should be relatively recent and included to aid in the interpretation of your results and/or linked to similar studies. If a study that you cited disagrees with your findings, don't ignore it--clearly explain why the study's findings differ from yours.


V.  Problems to Avoid

  • Do not waste entire sentences restating your results. Should you need to remind the reader of the finding to be discussed, use "bridge sentences" that relate the result to the interpretation. An example would be: “The lack of available housing to single women with children in rural areas of Texas suggests that...[then move to the interpretation of this finding].”
  • Recommendations for further research can be included in either the discussion or conclusion of your paper but do not repeat your recommendations in the both sections.
  • Do not introduce new results in the discussion. Be wary of mistaking the reiteration of a specific finding for an interpretation.
  • Use of the first person is acceptable, but too much use of the first person may actually distract the reader from the main points.
