mean deviation from the mean for the data

$4, 7, 8, 9, 10, 12, 13, 17$ is _____

The Karl Pearson's coefficient of skewness is

For calculating mean deviation, deviations cannot be taken from any average.

Calculation of mean deviation is based on observations unlike range or quartile deviation which considers only limits.

While measuring dispersion using mean deviation, the value is not affected as much by the extreme values.
