Quizplus · Accepted Answer

The Solomon four-group design is a research method that involves four groups to test the effects of a treatment or intervention. Two of the groups receive the treatment, with one of these groups receiving both a pretest and a posttest, and the other receiving only a posttest. The other two groups do not receive the treatment, with one undergoing both pretest and posttest, and the other only the posttest. This design helps to assess both the impact of the treatment and the effect of having a pretest.
