The student consistently uses correct mathematical notation, symbols, and terminology. Key terms and variables are defined and explained when first introduced, while additional terms are defined in detail in appropriate places. The main concepts are described in the introduction, along with crucial considerations and assumptions regarding the research. Multiple forms of mathematical representation are present, but only used if appropriate. All mathematical calculations are explained, and any data presentation is described. However, the student does not use a deductive method and set out logical proofs where appropriate. The graphs, tables, and diagrams are labeled at the bottom.
