Subgroups are categorical variables that can be included in your data file/study to enhance the results by providing subgroup analyses (or further breakdown of results). You may specify up to three additional subgroup variables using your own data. An example of a possibly useful subgroup for analysis is “College within the institution” (e.g., Arts and Sciences, Agriculture, Architecture, etc.).
Note: In order for subgroup analyses to run, you'll need at least 100 students in at least one level of the subgroup (e.g., 100 or more students in Arts and Sciences).
