The student fails to clearly state the independent and dependent variables in the research question, missing specific details such as the range of tension values. Additionally, the research question lacks a description of the method of analysis, which should include how the resonant frequency will be measured. While the student effectively includes a background theory and explains the choice of techniques for measurement, there is a need for improvement in discussing the rationale behind the number of trials conducted. Furthermore, the student does not address any ethical or environmental issues associated with the investigation. Despite these shortcomings, the methodology is well-described and free of irrelevant information, allowing for reproducibility of the investigation.
