1. A stem-and-leaf plot can help you compare data.
Stem-and-Leaf Plots
A stem-and-leaf plot can help you compare data.

2. The heights of 11 fourth-grade badminton players are (in inches):56 61 60 59 57 58 63 61 59

3. You can organize this data in a stem-and-leaf plot!

4. First, order your data from least to greatest.56 57 58 59 60 61 63

5. Then, put your data in a stem-and-leaf plot.

6. The ordered numbers are: 56, 57, 58, 58, 59, 59, 60, 61, 61, 61, 63
Each STEM stands for the first digit of each number.
Record the tens digits in order from least to greatest.
