Do taller people tend to have bigger hands? To investigate this question, each student in your class should measure his or her hand span (in cm) and height (in inches). Record these values in the table below.
Student | Hand Span (cm) | Height (inches) |
---|---|---|

2 | ||
3 | ||
4 | ||
5 | ||
6 | ||

Solutions will vary depending on the actual data values collected by the class. Below is a solution based on the following hypothetical data set:
Student | Hand Span (cm) | Height (inches) |
---|---|---|
1 | 17.0 | 64.0 |
2 | 21.0 | 67.0 |
3 | 20.3 | 65.0 |
4 | 26.0 | 72.0 |
5 | 24.0 | 71.0 |
6 | 22.0 | 70.0 |
7 | 21.0 | 66.0 |
8 | 19.0 | 62.0 |
9 | 20.0 | 73.0 |
10 | 19.0 | 65.0 |
11 | 17.8 | 68.0 |
12 | 20.5 | 62.0 |
13 | 21.0 | 70.0 |
14 | 22.8 | 73.5 |
15 | 22.6 | 67.0 |
16 | 21.0 | 72.0 |
17 | 23.0 | 74.0 |
18 | 21.6 | 70.0 |
