Question

Find the mean deviation about the mean for the data in Exercises. 38, 70, 48, 40, 42, 55, 63, 46, 54, 44

Philoid · Accepted Answer

We first find the mean (x̅) of the data

The respective absolute values of the deviations from mean, i.e., |x_i – x̅| are

12, 20, 2, 10, 8, 5, 13, 4, 4, 6

Therefore

And

Hence, the mean deviation about the mean for the given data is 8.4.
