The student does not clearly state the independent and dependent variables in the research question, which needs rephrasing for clarity. The method of analysis is also not specified, as the student fails to detail how heart rate will be measured. Additionally, there is an inadequate explanation of the choice of techniques for measuring the variables and the sampling technique used, which lacks justification. However, the student successfully identifies controlled variables, addresses safety, ethical, and environmental issues, and provides a clear outline of the methodology without irrelevant information. Overall, while some aspects are well-handled, significant improvements would have been needed in clarity and justification for the research design.
