Question

how do you calculate the standard deviation? take the square root of the variance. its a long process and i cant explain it right now. divide the variance by 2. find the mean and multiply it by the variance

Explanation:

Step1: Recall standard - deviation formula

The standard deviation $\sigma$ of a data - set is defined as $\sigma=\sqrt{\text{Variance}}$. So to calculate the standard deviation, we take the square root of the variance.

Answer:

Take the square root of the variance.
