The student clearly describes how the data was obtained and processed, providing a detailed methodology for data collection, which includes specific examples of the data collection process. However, the description of data recording and processing lacks detail and precision, as the tables do not have proper headings or units, making them unclear. Additionally, the student does not include considerations of uncertainties in the measurements, which would enhance the reliability of the data. While the validity of the conclusions is upheld due to controlled variables and relevant analysis, the data processing section requires further clarification to accurately address the research question.
