The student did not use correct mathematical notation consistently, as evidenced by the improper use of multiple equal signs in a single equation. The introduction failed to adequately describe the main mathematical concepts relevant to the investigation, lacking specificity about the mathematical tools and methods employed. Additionally, the student did not appropriately present data, as raw data should have been placed in an appendix, and the necessary explanations for mathematical calculations, such as how the P-critical value was determined, were missing. Furthermore, the degree of accuracy for rounded values was not stated, although the student did demonstrate an understanding of rounding results at the end of calculations. Finally, while the student rounded results correctly, the graphs, tables, and diagrams were not labeled properly, as the labels should have been placed at the bottom.
