What is Understanding Measures of Dispersion about?

Here are the steps to find the standard deviation for each batsman: Batsman A: 1) Mean = 25 2) Deviations from mean: 0, 0, 0, 0 3) Sum of squared deviations = 0 4) Variance = Sum of squared deviations / n = 0 / 4 = 0 5) Standard deviation = √Variance = √0 = 0 Batsman B: 1) Mean = 50 2) Deviations from mean: -50, -50, -50, 50 3) Sum of squared deviations = 50^2 + 50^2 + 50^2 + 50^2 = 10000 4) Variance =
