For both sets of data, the median is equal to the mean.
The interquartile range (IQR) is greater for M's classes than J's classes.

Median: 27
Mean: 27
Mean Absolute Deviation: 2.4
Interquartile Range: 3
<u>M's Classes:</u>
20, 24, 26, 29, 31
Median: 26
Mean: 26
Mean Absolute Deviation: 3.2
Interquartile Range: 5
N-9=14
that's just an example. what it equals to can be anything really
6m + 6m + 15m + 15m = 42m
no 40m will not be enough
