Quizplus · Accepted Answer

The Solomon four-group design includes both pretest and posttest measures for two separate groups, allowing for an assessment of the effects of the pretest experience on the outcome variable. This design does not necessarily decrease cost, limits external validity, and likely increases the overall cost due to the need for four separate groups.
