The student consistently uses correct mathematical notation, symbols, and terminology throughout the IA, demonstrating a solid understanding of relevant concepts such as expected goals (xG) and correlation coefficients. Key terms and variables are clearly defined and explained upon their introduction, and additional terms are elaborated on appropriately as the exploration develops. The introduction effectively outlines the main concepts, emphasizing the significance of the xG metric in football analysis. The student employs multiple forms of mathematical representation, including tables and graphs, and provides thorough explanations for all mathematical calculations, ensuring clarity and accuracy in data presentation. Results are rounded only at the end of calculations, and all graphs, tables, and diagrams are properly labeled, enhancing the overall readability of the work.
