The following data values represent a population. What is the variance of the values? 7, 5, 11, 1, 11

The mean is 35/5=7

The variance is the average of the sum of squared differences of each element from the mean:

v = ((7-7) ^2 + (5-7) ^2 + (11-7) ^2 + (1-7) ^2 + (11-7) ^2) / 5

v = (0+4+16+36+16) / 5

v=14.4
