E2E stub topic

EDEXCEL

GCSE

This subtopic focuses on the critical evaluation, selection, and construction of appropriate statistical diagrams to represent data accurately. Learners develop the ability to interpret graphical information in context, recognise misleading representations, and justify the choice of visualisation for specific data types. Practical application includes assessing real-world statistical claims and presenting findings clearly for decision-making.

Key skills and knowledge for this topic

Award credit for correctly labelling axes with units and providing a descriptive title.
Look for appropriate scaling that utilises the available graph area without distortion.
Credit explanations that link visual features to statistical properties (e.g., bar height proportional to frequency).
For critical evaluation, expect specific reference to how a graph might mislead (e.g., truncated axis, 3D effects).
