The student does not clearly describe how the data was obtained and processed, lacking explicit details on each procedural step, which reduces transparency. Additionally, the description of data recording and processing is not detailed or precise, as there are inconsistencies in significant figures across the tables. The student also fails to include considerations of uncertainties in the data, which is essential for evaluating the reliability of the results. Furthermore, there are significant omissions in the work that could hinder the validity of the conclusion, such as the absence of statistical analysis. Lastly, the data processing lacks clarity, as the student does not provide a step-by-step calculation example to demonstrate how averages were derived.
