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

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

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

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

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

7. 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. HEIGHTIN INCHES StemLeaves 5 6 6, 7, 8, 8, 9, 9 0, 1, 1, 1, 3

8. The ordered numbers are: 56, 57, 58, 58, 59, 59, 60, 61, 61, 61, 63 Each LEAF stands for the second digit of each number. Record the ones digits in order from least to greatest. HEIGHTIN INCHES StemLeaves 5 6 6, 7, 8, 8, 9, 9 0, 1, 1, 1, 3

9. You can use a stem-and-leaf plot to find the median and the mode.

10. MEDIAN Find the middle number in a set of numbers. The median is 59 inches. MODE Find the number that occurs most often in a set of numbers. The mode is 61 inches. HEIGHTIN INCHES StemLeaves 5 6 6, 7, 8, 8, 9, 9 0, 1, 1, 1, 3

11. Now, let’s try one on our own!

12. Here are the scores of our volleyball games in a stem-and- leaf plot!
