The student correctly describes and explains the research design as independent measures, providing a clear understanding of the techniques used in their study. They also accurately identify and explain the sampling technique as opportunity sampling. However, the student should have provided a clear description of any relevant characteristics of the research participants, such as their age, ethnicity, and gender distribution among groups. Additionally, the student appropriately explains their choice of participants based on specific criteria, excluding Psychology students. The controlled variables, along with the reasons for control, are clearly stated by the student. However, they should have listed all materials used instead of only including them in the appendices. The explanation for the choice of materials is not provided.
