the standard deviation of a set is 4. what is the variance
The variance can be calculated as the square of the standard deviation. Therefore, the variance is 16.
The variance is the square of the standard deviation. Therefore, to find the variance, you need to square the standard deviation. In this case, if the standard deviation is 4, the variance would be 16.
To find the variance, you first need to know the standard deviation. In this case, the standard deviation is given as 4.
The variance is a measure of how spread out the values in a data set are. It is calculated by squaring the standard deviation.
So, to find the variance, you can square the value of the standard deviation:
Variance = Standard Deviation^2
Variance = 4^2 = 16
Therefore, the variance of the set is 16.
