Students learn to plot a frequency diagram and polygon from a results table.

Later, as learning progresses, they use frequency polygons to compare multiple distributions.

**Differentiated Learning Objectives**

- All students should be able to plot and interpret a Frequency Diagram and Polygon for data presented in a frequency table.
- Most students should be able to plot and interpret a Frequency Diagram and Polygon for data presented in a grouped frequency table.
- Some students should be able to compare distributions using Frequency Polygons.
