Two data sets and their mean absolute deviations are shown.

Study the plots of each data set and then answer the questions below.

Why does Set A have a higher mean absolute deviation than Set B does?

Data Set A has a _, so it has a higher MAD.

Why is mean absolute deviation not a reliable measure of variability for Set A?

The smaller MAD of Set B suggests that most of the data is the mean than it is in Set A.
However, most of the data in Set B is _ spread out from the mean than is most of the data in Data Set A.
