Students learn to read data and calculate averages from a stem and leaf diagram.

As learning progresses, students go from interpreting stem and leaf diagrams to creating their own using an appropriate key.

**Differentiated Learning Objectives**

- All students should be able to plot a stem and leaf diagram.
- Most students should be able to plot and interpret the median, mode and range from a stem and leaf diagram.
- Some students should be able to compare data sets from a back-to-back stem and leaf diagram.
