Suppose that the effect size we wish to use is one where the three populations means are 480, 500, and 520, with the within-group standard deviation being 100. Using the first formula above, . Using the second formula, the population standard deviation of the means (with k, not k-1, in the denominator) is 16.33, so f = 16.33 ( 100 = .163.
