A.3Conciseness and relevance
Good
Criteria Feedback
- Clear investigation sequence with a logical progression from context and data selection through modelling, testing, subgroup analysis, and evaluation.
- Well-structured report with headings, a table of contents, and an accessible overall flow.
- Mostly relevant content that stays focused on the relationship between inflation and stock returns.
- The development is not consistently secure because some claims become stronger than the evidence supports.
- There is noticeable repetition, especially when discussing the Russian 2022 point and Ukraine’s apparent stability.
- The central analysis would be stronger if the key comparisons were developed more directly in the main body rather than frequently deferred to the appendix.

B.2Multiple representations
Good
B.3Clarity and consistency
Good
Criteria Feedback
- Appropriate mathematical language is used throughout, including correlation, regression, residuals, and hypothesis-test notation.
- Effective use of multiple representations such as tables, scatter plots, fitted lines, residuals, and algebraic models.
- Generally clear communication that helps the reader follow the statistical process.
- Notation is not consistently accurate, especially in the hypothesis-test section where statistics are mislabeled.
- Some calculations and symbols are inconsistent across the report, including the sign of the correlation coefficient and repeated rounding differences.
- The hypothesis-testing presentation is incomplete because the decision rule and inferential details are not communicated clearly enough.
