If the mean is 280, then the deviations are

**ExplanationCentral**, Monday, April 9, 2012 at 5:47pmThe deviation is the difference between a value and the mean.

So the deviations are:

(290-280) (270-280) (250-280) (300-280) (290-280)

This gives you: 10 -10 -30 20 10

The average is the sum of the numbers divided by the number of numbers (5).

so that would be 0/5 = 0.
