Since the study does not involve random assignment of subjects to groups, a true experimental design is not possible. In this case, a nonequivalent control group design would be appropriate. In this design, the researcher selects two groups that are as similar as possible and assigns one group to receive the intervention (treatment) and the other group to serve as the control group. However, since subjects are not randomly assigned to groups, there may be differences between the groups that could affect the study's results. As a result, this design is considered weaker than a true experimental design, but it is still a valid design option in situations where randomization is not feasible or ethical.
