IB Mathematics Applications & Interpretation (AI) SL Internal Assessment Example

The exploration has a recognizable line of development from context and data collection to statistical analysis and a conclusion.

Section headings, tables, graphs, and appendix placement make the work easy to navigate.

The research question remains visible throughout, and the focus on the two Ferrari drivers gives the exploration a clear scope.

Several claims are not logically consistent with the calculations, especially where the conclusion goes beyond what the chi-squared and correlation results support.

Some sections repeat similar commentary or drift into unsupported personal observations, which weakens conciseness.

The appendix organization becomes confusing in places, which interrupts the flow of the main argument.

Appropriate statistical language is used in many places, including correlation, regression, expected frequency, degrees of freedom, and hypotheses.

Multiple representations are included, such as raw tables, scatterplots, regression lines, rank tables, and contingency tables.

The main data and procedures are generally visible and readable for the reader.

Notation and terminology are sometimes inaccurate, especially when coefficients are interpreted as causation or when test results are described imprecisely.

Some representations are weakened by poor data handling, particularly the coding of non-finishes as zero.

Inconsistencies in totals, means, and coefficient calculations reduce clarity and consistency.
