The student clearly describes how the data was obtained and processed, making each procedural step easy to understand, as demonstrated by the systematic approach in preparing the iodine solution and controlling variables. However, the description of data recording and processing lacks detail and precision, particularly regarding the consistent application of uncertainty across tables. The student effectively addresses uncertainties in the data by calculating percentage uncertainties for key measurements, which enhances the understanding of data reliability. Nonetheless, there are significant inaccuracies in the calculations, such as potential arithmetic errors and inconsistencies in unit conversions, which could hinder the validity of the conclusions drawn. The student does conduct relevant data processing that accurately addresses the research question, as evidenced by the comprehensive presentation of raw and processed data, including effective use of graphs and statistical measures.
