www.csun.edu– Variability describes the distribution. • Specifically, it tells whether the scores lt d l t th are clustered close together or are spread out over a large distance. – Variability measures how well an individual score (or group of scores) represents the entire distribution. • This aspect of variability is very
Random Variability, correlation and covariance
www.kellogg.northwestern.eduRandom Variability: Covariance and Correlation What of the variance of the sum of two random variables? If you work through the algebra, you'll find that Var[X+Y] = Var[X] + Var[Y]+ 2 (E[XY] - E[X] E[Y]) . This means that variances add when the random variables are independent, but not necessarily in other cases.
