The student clearly described how the data was obtained and processed, making each procedural step easy to understand. The methodology for collecting both qualitative and quantitative data was well articulated, with detailed data recording and processing, including appropriately annotated tables and consistent use of units and significant figures. However, the student needed to expand on the impact of uncertainties on the data and results, particularly regarding how the reported average percentage uncertainty of 1.79% affected the reliability of the findings. Overall, the student's work contained no major omissions or inaccuracies that would undermine the validity of the conclusion, and the data processing was relevant and effectively addressed the research question.
