IMRaD is an acronym for Introduction, Methods, Results, and Discussion. It describes the format for the sections of a research report. The IMRaD (or IMRD) format is often used in the social sciences, as well as in the STEM fields.
With some variation among the different disciplines, most scholarly articles of original research follow the IMRD model, which consists of the following components:
Method & Results
This form is most obvious in scientific studies, where the methods are clearly defined and described, and data is often presented in tables or graphs for analysis.
In other fields, such as history, the method and results may be embedded in a narrative, perhaps describing and interpreting events from archival sources. In this case, the method is the selection of archival sources and how they were interpreted, while the results are the interpretation and resultant story.
In full-length books, you might see this general pattern followed over the entire book, within each chapter, or both.
