Quizplus · Accepted Answer

Dr. Fletcher is using a nonequivalent control group design by comparing those who joined a fraternity/sorority to those who did not, in order to investigate the effect of joining on body concern. Neither an interrupted time-series design, a nonequivalent groups interrupted time-series design, a reversal design, nor a stable-baseline design fit this study.
