The student fails to clearly state the independent and dependent variables in the research question, which is essential for understanding the investigation's focus. Additionally, there is no clear explanation of the choice of techniques for measuring these variables, nor is there a discussion regarding the sampling technique or the number of trials conducted. However, the student does provide a solid background theory relevant to the research question and identifies controlled variables, safety, ethical, and environmental issues effectively. The methodology is described sufficiently to allow for reproduction of the investigation, and there is no irrelevant or repetitive information present.
