Find the deviations from the mean for the numbers

32, 41, 47, 53, 57.

 

Solution:- Adding these numbers and dividing by 5 given a mean of 46.

To find the deviations from the mean, subtract 46 from each numbers in the list. For example, the first deviation from the mean is 32 – 46 = -14; the last is 57 – 46 = 11.
