Instructional Ideas

• Make a comparison with stem-and-leaf diagrams and other data displays, including advantages of each type of display

Classroom Considerations

• The class should be familiar with finding measures of center and variability from a data set
• Stem-and-leaf plots are not specifically mentioned in CCSS

Pros

• Stresses that a key must accompany the diagram
• The presenter uses different colors to help organize the data

Cons

• None
