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 the 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 the lack of causality between variables despite the apparent correlation.
