The student has effectively organized the Internal Assessment (IA) into clearly defined sections, including an introduction, body, and conclusion, which aids in navigating the investigation. The body is further subdivided to indicate the phases of exploration, with specific sections addressing univariate and bivariate analyses. While the topic is clearly stated in the introduction, the student does not sufficiently describe their approach to the investigation or specify the areas of the math curriculum that are relevant. Additionally, there are formatting issues, such as the need to center mathematical equations and provide introductory sentences for visual elements, which should be addressed to enhance clarity. Overall, the exploration maintains a logical flow, supported by relevant calculations and visualizations, but requires improvements in certain areas to meet all criteria.
