IMRaD format is often used for?

• A. Clinical trials only.
• B. Literature reviews.
• C. Lab reports and systematic research in the sciences and engineering.
• D. Theses in humanities.

Answer: (C)

IMRaD is a clear, standardized way to present experimental research by dividing the paper into Introduction, Methods, Results, and Discussion. This structure mirrors how scientific work unfolds: start with the problem and rationale, describe exactly how the study was conducted, report the data collected, and then interpret what the data mean in relation to the hypotheses. Lab reports and systematic research in science and engineering benefit from this format because it makes methods transparent for replication, shows the actual evidence in the results, and keeps interpretation in a separate section to avoid mixing data with conclusions. The format isn’t limited to clinical trials; it appears across many scientific fields. Literature reviews and humanities theses usually follow different structures focused more on synthesis and argument rather than a fixed four-part sequence.
