Solution
The standard deviation of the sampling distribution of a statistic is known as its Standard Error abbreviated as S.E.
| S.NO | Statistic | Standard Error |
| 1 | Sample mean | `sigma/sqrt("n")` |
| 2 | Observed sample proportion | `sqrt("PQ"/"n")` |
| 3 | Sample standard deviation | `sqrt(sigma^2/(2"n")` |
| 4 | Sample variance | `sigma^2 sqrt(2/"n")` |
| 5 | Sample quartiles | 1.36263 `sigma/sqrt("n")` |
| 6 | Sample median | 1.25331 `sigma/sqrt("n")` |
| 7 | Sample correlation coefficient | `((1 - "p"^2))/sqrt("n")` |
