Does the MAD represent a large or small amount of variability? Why?

The mean absolute value deviation is a measure of dispersion which gives the average variation of the data from the mean. In order words, it is the average of the positive distances of each point from the mean. The larger the Mean Absolute Deviation, the greater variability there is in the data (the data is more spread out).

The MAD helps determine whether the set's mean is a useful indicator of the values within the set.

The larger the MAD, the less relevant is the mean as an indicator of the values within the set.
