The student clearly describes and explains the research design, identifying it as a repeated measures design, which enhances the accuracy of assessing the effects of background music on memory recall. They also effectively detail the sampling technique used, which is convenience sampling, acknowledging its limitations while providing context regarding the age range of participants. However, the student fails to state relevant characteristics of the research participants, such as total numbers and gender distribution, and does not justify the choice of participants adequately. Additionally, they neglect to identify and describe the controlled variables, which affects clarity and reproducibility of the study. Nonetheless, the student successfully lists and clarifies the choice of materials used in the methodology, demonstrating a thoughtful approach to maintaining consistency and ethical standards in their research.
