Quizplus · Accepted Answer

The design described in the scenario is a nonequivalent control group design, which involves comparing a group that receives the treatment (joining a fraternity/sorority) to a group that does not receive the treatment (not joining a fraternity/sorority) but is otherwise similar. This design helps to control for potential confounding variables that could affect the outcome of the study. The other design options listed (interrupted time-series, nonequivalent groups interrupted time-series, and reversal designs) do not apply in this scenario because they involve different types of manipulations or measurements.
