The Solomon four-group design is a research method that involves four groups to assess the effects of a treatment or intervention. Two groups receive a pretest (one of these groups receives the treatment, and the other does not), and two groups do not receive a pretest (again, one of these receives the treatment, and the other does not). This design helps to evaluate both the impact of the treatment and the effect of having a pretest on participants' responses.
