The standard deviation of a dataset is the square root of the variance.
The standard deviation of the same set of data is 4
The variance is given as:

Take the square root of both sides to calculate the standard deviation

Substitute 16 for
.
So, we have:

Take the positive square root of 16

Hence, the standard deviation of the same set of data is 4
