Why is the formula 1 (x-x) not used as a measure of dispersion? Show mathematically (i.e., prove) for a set of observations x₁,x2,...,x why this formula fails to give useful information about the dispersion of the data. (Hint: You may want to calculate the formula for a few data points, but you still must show it mathematically for a general set of n observations.)
