The student clearly describes how the data was obtained and processed, making each procedural step easily understood. However, the description of data recording and processing lacks detail and precision, as tables and figures are not appropriately annotated, and the correct number of units, decimal places, and significant figures are not consistently applied. Additionally, there is a lack of clear considerations regarding the impact of uncertainties on the data and results, which could affect the reliability of the conclusions. The validity of the conclusions may also be hindered by inaccuracies in the calculations for the Spearman correlation coefficient, which need to be verified and clearly presented. Lastly, while the student has presented processed data, they have not included sample calculations that would accurately address the research question, requiring step-by-step demonstrations of how prevalence percentages were derived from the raw data.
