Find out what a stem-and-leaf graph is. Find out what a back-to-back stem-and-leaf graph is. Work through this tutorial to understand the features of stem-and-leaf graphs, and how they are used to display and to compare two data sets. Observe how the mean and median of the data sets can be used to interpret information. Look at examples of different data that can be used in a stem-and-leaf graph. This learning object is one in a series of five learning objects.
Objective
1. Students explore the features and uses of back-to-back stem-and-leaf graphs to display data.
2. Students observe how a stem-and-leaf graph is used to prove or disprove a conjecture.
3. Students examine the different uses of a stem-and-leaf graph.
