Calculate Standard Deviation and it's coefficient from the following data:
X: 100 90 120 110 80 70 150 130 50 100
Dear Student

| X | |
| 100 | |
| 90 | |
| 120 | |
| 110 | Mean = ∑X/ N |
| 80 | 1000/10 |
| 70 | 100 |
| 150 | |
| 130 | |
| 50 | |
| 100 | |
| N = 10, ∑X=1000 |
| X | dx = X-Mean |
| 100 | 0 |
| 90 | -10 |
| 120 | 20 |
| 110 | 10 |
| 80 | -20 |
| 70 | -30 |
| 150 | 50 |
| 130 | 30 |
| 50 | -50 |
| 100 | 0 |
| ∑|dX|=0 |
