Students learn how to plot scatter graphs to identify whether any correlation exists between to measurements.

As learning progresses students distinguish between types and strength of correlation and how to interpret this in context to the data presented.

**Differentiated Learning Objectives**

- All students should be able to plot a scatter graph when the scales are provided.
- Most students should be able to choose their own scales to plot a scatter graph.
- Some students should be able to determine whether two measurements correlate by plotting a scatter graph and line of best fit.
