Students use and plot scatter graphs to understand how correlation may not imply mean causation. As learning progresses students look for external factors that may explain correlation.
Differentiated Learning Objectives
- All students should be able to recognise when one variable causes a change in another.
- Most students should be able to understand the limitations of scatter graphs in identifying causal relationships.
- Some students should be able to suggest reasons for lack of causality between variables despite correlation being apparent.
