Quizplus · Accepted Answer

A two-group design is a type of experimental design where different participants are assigned to each of the groups being compared, which is a hallmark of between-subjects methodology. In contrast, repeated measures, mixed designs, and pretest-posttest designs involve measuring the same participants under different conditions or at different times, which are characteristics of within-subjects or mixed methodologies.
