This calculator finds the

**standard error of the mean**of a given set of numbers using the following formula:**Standard error of the mean**= s / √n

where

*s*is the sample standard deviation and*n*is the sample size.To find the standard error of the mean, simply enter the comma-separated values of the dataset in the box below and then click the “Calculate” button.

Standard error = **4.347961**

**Explanation:**

Sample standard deviation (s) = 11.503623

Sample size (n) = 7

Standard error = 11.503623 / √7 = **4.347961**
