The average (arithmetic mean) of 7 different numbers is 5 Column A Column B Median of the 7 numbers 5
Cannot be detirmented
Set X: {5, 6, 9} Set Y: {0, 1, 4}
Equally disporosed
Set A: {0.2, 0.4, 0.6, 0.8} Set B: {2, 4, 6, 8} Column AColumn BStandard deviation of set AStandard deviation of set B
So in Set A, the first number, 0.2, deviates from the mean, 0.5, by only 0.3, whereas in Set B, the first number deviates from the mean, 5, by 3, which is a much larger value. Even if proportionally these two sets look very similar, it is these direct values (0.3 vs. 3) that we compare when we are comparing the standard deviations.
