Research Paper Structure: The IMRaD Format Explained

IMRaD stands for Introduction, Methods, Results, and Discussion - the standard structure for empirical research papers in sciences, health sciences, and quantitative social sciences. Each section answers a specific question: Introduction (why this study?), Methods (how was it done?), Results (what was found?), Discussion (what does it mean?). Modern IMRaD papers also include an Abstract, Conclusion, and References.

Introduction (~10% of word count): establish the field, summarise existing knowledge, identify the gap, state your research question and hypotheses, preview the study.

Methods (~20-25%): design, participants, materials, procedure, data analysis, ethics. Should be detailed enough that another researcher could replicate the study.

Results (~20-25%): present findings in tables and figures with concise narrative. State what was found, not what it means - interpretation belongs in Discussion.

Discussion (~25-30%): interpret findings, link back to the literature, acknowledge limitations, suggest future research. Open with a one-paragraph summary of your headline finding.

Conclusion (~5%): restate the contribution, name practical implications, suggest next steps. Avoid introducing new evidence.

Abstract (150-300 words): mini IMRaD covering background, methods, results, and conclusion. Most readers only read the abstract - make it count.
