Find the mean deviation about the mean for the following data :
39, 72, 48, 41, 43, 55, 60, 45, 54, 43
We have, 39, 72, 48, 41, 43, 55, 60, 45, 54, 43
Mean of the given data is
The respective absolute values of the deviations from mean , i.e are
11, 22, 2, 9, 7, 5, 10, 5, 4, 7
Thus, the required mean deviation about the mean is
