Remember that variance is a measure of dispersion of data, meaning that it measures how close all measurements to the mean of the sample or population. A. (x B : This column is the difference between each measurement and the mean value. In essence, this is the basis of variance. However, because the average and sum of these values will always be zero, we cannot use these values as they are to give a picture of dispersion. This value has little value in characterizing the population but is an important intermediate step in calculatine variance
