Explanation:

The interquartile range of a data set is the difference between the first quartile and the third quartile of the data set.

First, find the first quartile, which is the median of the first half of the data set. Then, find the third quartile, which is the median of the second half of the data set. Last, subtract the value of the first quartile from the value of the third quartile.

So, the interquartile range of the data set is 5.

The mean absolute deviation of a data set is the average distance between each data value and the mean.

First, find the mean of the data set.

Now, find the distance each data value is from the mean, 12.4.

Now, find the mean of the distances the values are from 12.4.

The mean absolute deviation of the data set is 3.6.
