Quizplus · Accepted Answer

A Solomon four-group design involves randomly assigning participants into one of four groups: one group receives both pretest and posttest, one group receives only the posttest, one group receives only the pretest, and one group receives neither. This design allows for a comparison of the effects of pretesting on the posttest outcomes, while also controlling for any other factors that could affect the results. Therefore, it is a good choice when there is concern over the possible impact of taking the pretest.
