The student does not consistently use correct mathematical notation, symbols, and terminology, particularly with the mean symbol and summation notation, which could enhance clarity. Key terms and variables, such as height and foot size, are not defined upon their introduction, which would aid in reader comprehension. While the main concepts of the investigation are well described in the introduction, and various mathematical representations are effectively utilized, the student fails to explain all mathematical calculations and data presentations, leaving gaps in understanding. Furthermore, the degree of accuracy for rounded values is not stated, and results are not rounded only at the end of the calculation thread as required. However, the student successfully labels and numbers all graphs, tables, and diagrams, contributing to the overall clarity of the exploration.
