Mean is the average value of a set of results. It's the sum of all the results divided by the number of results.

Sum is an answer to an addition problem.
The sum of total deviations about the mean is the total variance. * * * * * No it is not - that is the sum of their SQUARES. The sum of the deviations is always zero.
The mean of a series is equal to the sum divided by the number of items in the series. So, mean = sum/number, which means the sum is equal to the mean times the number. In this case, the sum is 3573.
