For which measure of central tendency will the sum of the deviations always be zero?
the mean
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.
0 (zero).

No, it is not, values typical of the data are always located at the extremes of all data frequencies.
Mean and median are the measures of central location that always have one value. This is true for a set of grouped or ungrouped data.
