The research report is structurally unlike any other academic assignment. Standard essays build an argument from a thesis. Literature reviews synthesise existing sources. Reflective essays follow a model. But a research report follows a logic determined by the scientific method itself — one that separates data collection from data interpretation by design, not by convention.
This separation exists for a reason: it forces the writer to distinguish between what the data objectively shows and what it might mean, preventing the most common form of academic bias — letting your interpretation shape how you report your findings. Understanding this logic is the key to understanding IMRaD, and it's what this guide builds from the ground up.
The unique framework in this post is the Results vs Discussion Firewall — a concrete, visual breakdown of exactly what is permitted in each section and what must stay on the other side of the dividing line. It solves the most common structural error in research reports with a single, memorable rule.

The IMRaD Framework — Why Research Reports Follow a Different Logic
IMRaD stands for Introduction, Methodology, Results, and Discussion. It is the internationally recognised structure for empirical research reports across sciences, social sciences, health, psychology, and business. The Abstract sits before all four sections; the Conclusion follows them.
Each section answers one specific question and one question only. This is not a stylistic choice — it is a structural principle. A Results section that starts interpreting findings has crossed into Discussion territory. A Discussion section that introduces new data has crossed back into Results territory. Both are structural errors that weaken the report's credibility and cost marks.
The Results vs Discussion Firewall
This is the dividing line most students breach. Here is exactly what belongs on each side:
The test for every sentence in your Results section: "Am I reporting a finding, or interpreting it?" If interpreting — move it to Discussion. The test for every sentence in your Discussion: "Am I introducing new data, or analysing existing findings?" If introducing new data — move it to Results.
Research Report Word Count Breakdown by Section
Research report word counts are typically allocated differently from essay word counts. The Methodology and Discussion sections receive the largest allocations because they require the most technical detail and analytical depth respectively.
| Section | 2,000 Words | 3,000 Words | 5,000 Words | 8,000 Words | % |
|---|---|---|---|---|---|
| Abstract | 150 | 200 | 250 | 300 | 4–7%* |
| Introduction | 300 | 420 | 650 | 960 | 12% |
| Methodology | 400 | 600 | 1,000 | 1,600 | 20% |
| Results | 300 | 450 | 750 | 1,200 | 15% |
| Discussion | 550 | 900 | 1,600 | 2,560 | 32% |
| Conclusion | 200 | 300 | 500 | 800 | 10% |
| References (not counted) | — | — | — | — | — |
| Total | 1,900 | 2,870 | 4,750 | 7,420 | ~100% |
*Abstract word count is often fixed by the brief (150–300 words). Check your assignment guidelines. Remaining words distributed across other sections.
How to Write Each Section of a Research Report
Abstract — Write This Last
The abstract is a self-contained summary of the entire report: aim, methods, key findings, and main conclusion — one to two sentences each. It is written last because it summarises the completed report. Most abstracts are 150–250 words. Critical rule: the abstract should be readable in isolation — someone who reads only the abstract should understand what the research did and found, without needing to read the full report.
150–300 words | Write after everything elseIntroduction — Why Did You Do This Research?
The research report introduction has a specific three-part structure: background context (what is known in this area), gap or problem (what is not yet known, or what problem exists), and research aim or question (what this study sets out to address). This is sometimes called the "funnel" structure — broad context narrows to a specific research question. End the introduction with a clear statement of your research aim, objectives, or hypotheses. Do not preview your findings here.

The Methodology section must be detailed enough that another researcher could replicate your study. It covers: research design (quantitative, qualitative, or mixed methods), sampling strategy (who participated and how they were selected), data collection instruments (survey, interview, observation, etc.), procedure (step-by-step account of how data was collected), and ethical considerations. The test for every sentence: could someone replicate this study from what I've written? If not, add more detail. The Methodology section is not the place for results or justification of your findings — only your process.
~20% of total word countResults — What Did You Find?
Report your findings clearly and objectively, without interpretation. Organise results logically — either by research question/hypothesis, or by theme for qualitative studies. Use tables, figures, and charts where they communicate data more efficiently than prose. Every table or figure must be referenced in the text ("As shown in Figure 2...") and every visual element must have a clear title and label. The golden rule: describe what the data shows, never why it shows it. That belongs in Discussion.
~15% of total word countDiscussion — What Does It Mean?
The Discussion is the analytical core of a research report and receives the largest word count allocation for this reason. It interprets your findings in light of the existing literature, explains unexpected or contradictory results, acknowledges limitations of the study, and discusses the implications of your findings for theory, practice, or policy. Structure it by mirroring your Results section — address each finding in the same order it appeared in Results. Each interpretive point should reference both your findings and relevant literature. Limitations should be specific and honest, not generic disclaimers.

The conclusion restates the research aim, summarises the key findings (two to three sentences), and states the overall answer to the research question. Recommendations follow — specific, actionable suggestions for practice, policy, or future research that emerge directly from your findings and discussion. Recommendations in a research report follow the same rule as in a case study essay: they must be specific, feasible, and grounded in the evidence. "Further research is needed" without specifying what kind is not a recommendation.

Before submitting, read your Results section and highlight every sentence that contains a "why" or "because" — these belong in Discussion. Then read your Discussion and highlight every sentence that introduces data not already in Results — these belong in Results or should be cut. This single check catches the most common structural error in research reports.
Discussion Should Mirror Results
Structure your Discussion section in the same order as your Results section. If Results covers Finding A, then Finding B, then Finding C — Discussion should interpret Finding A, then B, then C in the same sequence. This parallel structure makes the report easier to read and signals to the marker that you understand how the two sections relate.
Write the Abstract Last, Not First
The abstract summarises a completed report. Students who write it first either produce an inaccurate summary (because the report hasn't been written yet) or constrain the report to match the abstract. Write the full report first, then distill it into the abstract. It should take 20–30 minutes to write once the report is complete.
How Structure Changes at Different Word Counts
| Word Count | Methodology Detail | Results Depth | Discussion Focus |
|---|---|---|---|
| 2,000 words | Overview of design and procedure | Key findings only | 2–3 interpretive points with literature |
| 3,000 words | Full design, sampling, and ethics | All findings with descriptive statistics | 4–5 interpretive points, limitations paragraph |
| 5,000 words | Detailed justification of methods chosen | Sub-themes or sub-groups analysed | Theoretical framework engagement, implications |
| 8,000+ words | Epistemological positioning, pilot study notes | Full statistical or thematic analysis | Extended literature comparison, policy implications |
Common Mistakes in Research Report Structure
Mixing Results and Discussion. The most common and most penalised structural error in research reports. Sentences like "Participants reported high stress levels, which suggests that the intervention was ineffective" belong in two different sections: the observation belongs in Results; the interpretation belongs in Discussion. Keep these sections cleanly separated using the Firewall test on every sentence.
Writing the Abstract first. An abstract written before the report is complete is either a plan (which will need rewriting) or a constraint (which limits where the report goes). Write the abstract last. It should accurately summarise the completed report — aim, methods, findings, and conclusion — in 150–300 words.
A Methodology section too vague to replicate. "Data was collected through interviews" is not a methodology — it's a one-line description. The test is replicability: could another researcher reproduce your study from what you've written? If not, the Methodology is incomplete. Include sample size, selection criteria, data collection instrument, procedure, and ethical approval.
Generic limitations in the Discussion. "The sample size was small" and "the study had limitations" are filler. Specific limitations name the actual constraint and explain its impact on the findings: "The convenience sample of 23 undergraduate students limits generalisability to the broader population, as this group may not represent the range of experiences found in professional settings." Specific limitations demonstrate critical awareness; generic ones demonstrate avoidance.
A conclusion that simply restates the Discussion. The conclusion of a research report is not a summary of the Discussion — it answers the research question directly. One to two sentences per key finding, a direct answer to the research aim, and specific recommendations. If your conclusion reads as a paragraph-by-paragraph recap of the Discussion, condense it into a direct, focused answer to the original research question.
