Variance (measure of dispersion) - a measure of the average squared deviation around the sample mean: s #1 (x - x) i=1 n-l Standard deviation (measure of dispersion) - the square root of the sample variance: S= (x - x) i=1 n-1 (6) It is only defined if x > 0. Standard error (measure of dispersion) - the standard error of the mean: n (7) Coefficient of variation or relative standard deviation (measure of dispersion) - measures the magnitude of the standard deviation as a percentage of the sample mean according to: CV = 100-% (8) (9)
