Yalda is a research scholar in the Department of Psychology at University of Umbria. She wants to compare the effectiveness of moral education with that of threats of social and financial coercion as a deterrent to tendencies of cheating and corruption. She has resorted to random assignment of the participants to the groups to remove any systematic bias. But, neither Yalda nor the participants have the required amount of time or scope to delve into the treatment specific change of the dependent variable in each participant. She wants her study to have minimal unknown variances to the dependent variable. She does not want threats to internal validity such as history, maturation, order effects, and sequence effects to dilute the effectiveness of her findings. Which of the following research designs is suitable for her study?

The posttest-only control group design is suitable for Yalda's study because it allows for random assignment of participants to groups and minimizes threats to internal validity (such as history and maturation) by not including a pretest or crossover design. Additionally, it is a practical option given the time and scope constraints of the study.
