For a group of 50 male workers the mean and standard deviation of their daily wages are 63 dollars and 9 dollars respectively. for a group of 40 female workers these values are 54 dollars and 6 dollars respectively. find the mean and variance of the combined group of 90 workers. solution:. Definition of variance ˙2 = var(x) def: variance let x be a random variable (discrete or continuous) with a finite mean = e(x). the variance of x is defined as var(x) = e (x )2 the standard deviation of x is defined as p var(x) we often use ˙2 for variance and ˙for standard deviation. theorem 4.3.1 – another way of calculating variance.
