The student demonstrates consistent and correct use of mathematical notation, symbols, and terminology throughout the investigation. They appropriately define and explain key terms/variables when first introduced. The main concepts are described in the introduction, and additional terms are defined in detail in appropriate places. Multiple forms of mathematical representation, such as formulae, diagrams, tables, charts, graphs, and models, are present and used appropriately. Mathematical calculations are explained, and any data presentation is described. The student also states the degree of accuracy for any rounded values. However, the student should provide commentary on the inclusion of values from the statistical software to compensate for rounding before the end of the calculation thread. Overall, the student uses a deductive method and provides logical proofs where appropriate. The graphs, tables, and diagrams are labeled at the bottom, indicating a clear understanding of their purpose.
