The data for the group that plays an instrument are more clustered around the mean than the data for the group that did not play an instrument.

The data for the group that does not play an instrument are more spread out than the data for the group that does play an instrument The mean absolute deviation for the group of students who do not play an instrument is 2. The data for the group that does not play an instrument are more clustered around the mean than the data for the group that does play an instrument.
If you're looking for direct correlation, you're looking for a proportion for the second box. So you set the ratio of 2.5:5.5 up as a fraction. 2.5/5.5 and set it equal to the second box 3/x.
