Students learn how to compare distributions using stem and leaf diagrams.

Later, as learning progress students are challenged to compare two data sets using back to back stem and leaf diagrams.

**Differentiated Learning Objectives**

- All students should be able to calculate the median and range from an ordered stem and leaf diagram.
- Most students should be able to compare a back to back stem and leaf diagram using the median and range.
- Some students should be able to plot and compare a back to back stem and leaf diagram using the median and range.
