The variance for the sample is 25
For given question,
We have been given the sample size n = 21
and the sum of squares is SS = 500
We need to find the variance for the sample.
We know that the variance is mathematically represented as,
Substituting given values in the above formula,
= 500 / 20
= 25
So, the variance is 25
Therefore, the variance for the sample is 25
