let me know if you need any clarification..
| Number | Value | =(value - 20.85)^2 | ||
| 1 | 10 | 117.64 | ||
| 2 | 18 | 8.10 | ||
| 3 | 24 | 9.95 | ||
| 4 | 30 | 83.79 | ||
| 5 | 19 | 3.41 | ||
| 6 | 22 | 1.33 | ||
| 7 | 24 | 9.95 | ||
| 8 | 20 | 0.72 | ||
| 9 | 18 | 8.10 | ||
| 10 | 25 | 17.25 | ||
| 11 | 20 | 0.72 | ||
| 12 | 22 | 1.33 | ||
| 13 | 19 | 3.41 | ||
| Total | 271 | 265.69 | ||
| Mean =271/13 | 20.85 | |||
| Variance = | =(265.69/(13-1)) | |||
| Variance = | 22.14 | |||
| therefore answer = | 22.14 | |||
