Question

The data below are the test scores of the students in a math class.

97, 76, 84, 82, 90, 95, 77, 79, 80, 82, 84, 77, 100, 78, 87
Create a stem-and-leaf plot to represent the data.

how???​

Answer 1

First, we can order the set in ascending order to get

76,77, 77, 78,79, 82, 82 ,84, 84, 87, 90, 95, 97, 100.

A stem-and-leaf plot has the tens digits on the left side, and the units digits on the right side, so this set would look like

7 | 6, 7, 7, 8, 9

8 | 2, 2, 4, 4, 7

9 | 0, 5, 7

10 | 0
