The student has effectively described and explained the research design chosen as independent measures, demonstrating a clear understanding of how it was applied in their study. Additionally, the sampling technique of opportunity sampling is correctly identified and explained, although the student could further elaborate on their choice of this technique. Relevant characteristics of the research participants are described, but the student could enhance their description by including the gender distribution and cultural backgrounds of the participants. The student has justified their choice of research participants based on English proficiency and has clearly stated all controlled variables, providing appropriate reasons for control. However, the explanation for the choice of materials, particularly the video of the collision, questionnaires, and debriefing documents, could be more comprehensive.
