Students learn about averages using the median and mode. As learning progresses they use the averages to compare sets of data.

At the start of the lesson they compare two bar charts. In the main part they learn how to find the median and mode and understand the benefits of each. The plenary challenges students to find the median and mode from charts rather that numerical lists.

**Differentiated Learning Objectives**

- All students should be able to find the mode from a bar or pie chart.
- Most students should be able to calculate the median and mode from a set of data
- Some students should be able to calculate the median and mode from a set of data and recognise the limitations of each average.
