The student clearly describes how the data was obtained and processed, making each procedural step easily understood, as evidenced by their documentation of initial and final burette readings during titration. However, the description of data recording and processing lacks detail, particularly in ensuring that all numerical values in the data tables maintain a consistent number of decimal places, which is essential for clarity and precision. The student effectively considers the impact of uncertainties on the data and results, demonstrating this through clear calculations of percentage uncertainty, which supports the reliability of their findings. Additionally, there are no significant omissions or inaccuracies that hinder the validity of the conclusions drawn from the experiment, as the data collected supports the hypothesis regarding the relationship between brewing temperature and polyphenol concentration. The student conducts relevant data processing that accurately addresses the research question, showcasing a clear correlation between variables through well-presented graphs and calculations.
