Suppose the average grade point average (GPA) for the undergraduate student population at Goldey-Beacom College is 3.10. The following list is a random sample of the GPAs of five students from the college. Caclulate the sampling error.
2.45 3.76 3.48 2.81 3.34
Solution
hence the sampling error is
| x | (x-3.10)^2 | sum((x-3.10)^2) | sum((x-3.10)^2)/5 | sqrt( sum((x-3.10)^2)/5 ) | |
| 2.45 | 0.4225 | 1.1442 | 0.22884 | 0.47837224 | |
| 3.76 | 0.4356 | ||||
| 3.48 | 0.1444 | ||||
| 2.81 | 0.0841 | ||||
| 3.34 | 0.0576 | ||||
