How to Write the Discussion Chapter of a Thesis: Examples and Tips

Key Takeaways

• The Results section reports what was found; the Discussion section explains what it means, why it matters, and how it fits existing research.
• Strong discussion chapters restate findings briefly using varied phrasing, then move quickly into interpretation, comparison with literature, implications, and limitations.
• A well-organized discussion follows a predictable arc: orientation, brief findings summary, interpretation, literature comparison, implications, limitations, recommendations, and a closing summary.

What Is the Difference Between the Results and Discussion Sections?

The Results section presents data objectively, with no interpretation; the Discussion section explains what that data means, why it occurred, and how it connects to prior research and theory.

Common mistake: Many students interpret results while still in the Results section, or simply repeat numbers in the Discussion section instead of explaining them. Keep description in Results and explanation in Discussion.

How Does the Discussion Chapter Differ From the Conclusion?

The Discussion chapter interprets each finding in depth and engages closely with the literature; the Conclusion chapter steps back to summarize the whole thesis briefly and state its overall contribution.

In many theses, especially at the Master’s and Bachelor’s level, the Discussion and Conclusion are combined into a single chapter. Where this happens, use clear subheadings so the interpretive discussion and the final summary remain distinguishable.

How to Write the Discussion for Different Research Methods

The structure of a discussion chapter shifts depending on whether the underlying study is qualitative, quantitative, or mixed methods, because each approach produces a different kind of evidence to interpret.

What Belongs in a Discussion for Qualitative Research?

A qualitative discussion interprets themes and patterns, situates them within participants’ own words and contexts, and connects them to theory rather than to statistical significance.

• Organize the discussion around themes or research questions, not around individual participants or interview questions.
• Interpret meaning: explain why a theme emerged and what it reveals about the phenomenon under study.
• Use illustrative participant quotations very sparingly, and follow each with interpretation rather than letting the quotation stand alone.
• Connect themes to existing theoretical frameworks, showing where the data confirms, extends, or challenges them.
• Address researcher reflexivity where relevant, acknowledging how the researcher’s position may have shaped interpretation.

What Belongs in a Discussion for Quantitative Research?

A quantitative discussion interprets statistical patterns, explains their practical significance, and compares effect sizes and directions of relationships with those reported in prior studies.

• Organize the discussion around research questions or hypotheses, in the same order used in the Results section.
• Distinguish statistical significance from practical or clinical significance, and report effect sizes where possible.
• Explain unexpected results, including non-significant findings, rather than omitting them.
• Compare your findings numerically and directionally with previous studies, not just topically.
• Discuss possible confounding variables or alternative explanations for the observed relationships.

What Belongs in a Discussion for Mixed Methods Research?

A mixed methods discussion integrates the quantitative and qualitative strands, showing where they converge, diverge, or explain one another, rather than discussing each strand in isolation.

• Use a joint display, narrative weaving, or side by side comparison to show how the two strands relate.
• Explain convergence: where quantitative patterns and qualitative themes point to the same conclusion.
• Explain divergence: where the two strands disagree, and offer a plausible explanation for the discrepancy.
• Show how qualitative data helps explain the mechanisms behind a quantitative result, or vice versa.
• Avoid a purely sequential structure that reads as two separate, unconnected discussions.

Common Phrases Used to Restate Results Without Repeating Them

Restating a finding should orient the reader in one sentence, not recite the numbers already shown in a table. Pair a brief restatement with an interpretive phrase in the same sentence.

How to Comment on the Results

Commenting on results means moving beyond description into evaluation and application: judging how strong or reliable a finding is, and stating what should follow from it.

How Do You Evaluate the Results?

Evaluating results means judging their strength, consistency, and reliability, not simply restating them or declaring them good or bad without justification.

• Assess consistency: does the finding align with, or contradict, the majority of prior research?
• Assess strength: is the effect size, theme prevalence, or pattern strong, moderate, or weak, and how confident can readers be in it?
• Assess plausibility: does the finding make theoretical or practical sense given what is already known?
• Assess robustness: would the finding likely hold under a different sample, setting, or method?

How Do You Make Suggestions Based on the Results?

Suggestions translate a finding into a concrete next step for practice, policy, or future research, phrased as a specific action rather than a vague hope.

• Tie every suggestion explicitly to the finding that produced it, using a phrase such as, because this study found X, it is suggested that Y.
• Prefer specific, actionable suggestions over general ones, such as naming which practice, policy, or population should change.
• Distinguish suggestions with strong evidential support from more tentative ones based on limited or exploratory data.
• Avoid suggestions that go beyond what the data can support, since overreach undermines credibility.

How Can You Avoid Repetition Between the Results and Discussion Sections?

Avoid repetition by referring readers back to tables and figures instead of re-describing them, and by organizing the discussion thematically around meaning rather than sequentially around each result.

• Refer to figures and tables by number, for example, as shown in Figure 2, rather than restating every value.
• Group related findings by theme or implication instead of walking through results in their original order.
• Open each discussion paragraph with interpretation or comparison, not with a restated number.
• Use one short orienting clause per finding, then spend the rest of the paragraph explaining significance.
• Cut any sentence from the Discussion that could be pasted unchanged into the Results section.

How to Start a Discussion Chapter

Open the Discussion chapter with a short orientation paragraph: restate the research aim in one sentence, briefly summarize the overall pattern of findings, and preview how the chapter is organized.

Sample opening sentences:

“This chapter interprets the findings presented in Chapter 4 in relation to the study’s research questions and the existing literature.”

“The purpose of this study was to examine X; the findings, summarized briefly below, are discussed in relation to prior research in the sections that follow.”

“Overall, the results provide partial support for the study’s hypotheses, with several notable exceptions discussed in this chapter.”

“This chapter is organized around the three research questions introduced in Chapter 1, followed by a discussion of implications, limitations, and recommendations.”

How to Close a Discussion Chapter

Close the Discussion chapter with a short synthesis paragraph that draws the interpretation together and signals the transition into the Conclusion, without introducing new findings or citations.

Sample closing sentences:

“Taken together, these findings suggest that X plays a more significant role in Y than previously recognized in the literature.”

“While several limitations, discussed above, constrain the certainty of these conclusions, the overall pattern of evidence supports the study’s central argument.”

“The following chapter summarizes these interpretations and considers their broader significance for theory and practice.”

“In sum, this study extends prior work on X by demonstrating that Y, while also identifying important questions for future research.”

How Do You Identify Research Implications?

Implications are identified by asking, for each major finding, so what: what changes for theory, practice, or policy if this finding is true, and for whom does it matter?

List implications separately from recommendations: an implication describes a consequence of the finding, while a recommendation prescribes a specific action.

How to Identify and Describe Research Recommendations

Recommendations should flow directly from the implications already discussed, and should be sorted by audience so readers can quickly find the guidance relevant to them.

• Practice recommendations: specific changes to professional practice, protocols, or procedures.
• Policy recommendations: specific changes to organizational, institutional, or governmental policy.
• Future research recommendations: specific gaps, populations, methods, or variables that future studies should address.
• Each recommendation should name a concrete action, an intended audience, and, where possible, the finding that justifies it.

Sample phrasing: it is recommended that healthcare providers adopt X protocol when treating Y population, given the association identified between X and improved Z outcomes in this study.

How to Identify and Describe Research Limitations

Limitations should be identified honestly across five common categories, and described in a way that explains how each one affects the interpretation of findings without dismissing the study’s value.

Tip: For each limitation, add one clause explaining its likely effect on the findings, for example, because the sample was drawn from a single clinic, results may not generalize to rural populations.

What Are the Differences Between PhD, Master’s, and Bachelor’s Discussion Chapters?

PhD discussions foreground an original, generalizable contribution to theory; Master’s discussions balance interpretation with applied relevance; Bachelor’s discussions focus on clear, well supported interpretation of a smaller study.

Frequently Asked Questions

How long should a discussion chapter be in a thesis?

Length varies by degree level and discipline, but a discussion chapter commonly runs from 5 to 12 pages for a Bachelor’s thesis, 10 to 20 pages for a Master’s thesis, and 20 to 40 pages for a PhD thesis.

What verb tense should I use in a discussion chapter?

Use past tense to describe what the study found, and present tense for statements about established knowledge, ongoing implications, or general truths, for example, this study found that X increased Y, which suggests that Z remains an important factor. Professional thesis editing, such as by Editage, can help you ensure correct tense and grammar throughout this chapter.

How do I discuss unexpected or contradictory results in a thesis?

Report the unexpected result plainly, propose one or more plausible explanations grounded in the literature or study design, and avoid either dismissing it or overstating its meaning beyond what the data support.
