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

The student's exploration has a clear overall route from data collection to analysis and conclusion.

The student uses headings, tables, graphs, and appendices in a way that makes the investigation easy to navigate.

Most of the material stays focused on the research question.

Some of the later methods do not grow naturally out of the earlier analysis.

A few sections interrupt the flow, and the numbering and model presentation are not fully consistent.

Several model comparisons feel repetitive rather than selective.

The student uses a good range of statistical language such as quartiles, expected frequency, regression equations, and percentage error.

Multiple representations are used effectively, including tables, plots, and model equations.

The main mathematical ideas are usually communicated clearly enough to follow.

Notation is sometimes inconsistent or imprecise.

Some graphs and model displays are not integrated cleanly into the written explanation.

A few labels, intervals, and calculations are presented in ways that make verification difficult.
