Here’s an example:
| Student |
Score |
Deviation Score(Residual) |
| Bill |
9 |
9 - 7 = 2 |
| Mary |
6 |
6 - 7 = -1 |
| Fred |
7 |
7 - 7 = 0 |
| Tom |
4 |
4 - 7 = -3 |
| Bea |
9 |
9 - 7 = 2 |
| Total |
35 |
|
| Average (Mean) Score = 35 / 5 = 7.0 |
The deviation value of a given data value is the difference between that data value and the mean.
