Both the for-mulas that express the Gini's Mean Difference in terms of the arithmetic mean and in terms of the median reduce to the following formula, which I regard as computationally simplest: N GMD= 2 X ixi - x N(N + 1) i=1 N(N - 1)/2 where the xi are the order statistics and the i WebThe mean difference is a measure of statistical dispersion equal to the average absolute difference of two independent values drawn from a probability distribution. A related statistic is the relative mean difference, which is the mean difference divided by the arithmetic mean. mfc l2700dw toner office depot
