Difference (deviation) from the mean.

Its the one most commonly used but outliers can seriously distort the mean.
The mean deviation of a set of observations is always zero and so conveys no information whatsoever!
No. It cannot be. Remember that when you square a negative number it becomes a positive number. Thus all squared deviations are positive and their sum must be positive.
For which measure of central tendency will the sum of the deviations always be zero?
yes is it the median?
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.
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.
