The student demonstrates consistent and correct use of mathematical notation, symbols, and terminology throughout the work. Key terms and variables are appropriately defined and explained when first introduced. However, the introduction lacks a description of relevant mathematical concepts such as normal distribution and the Shapiro-Wilk test, which is essential for the reader's understanding. Additionally, the student should ensure that all mathematical calculations and data presentations are thoroughly explained. It is important to state the degree of accuracy for rounded values, and to round results only at the end of the calculations thread. Finally, the graphs, tables, and diagrams are appropriately labeled at the bottom, contributing to the clarity of the presentation.
