The interquartile range of the set of data is 16.

Step-by-step explanation:

You first rearrange the set of data from lowest to highest.

6,13,15,19,19,20,25,26,31,38,41

Then you make the boxset around the median(50th percentile) which is 20.

Your 25th percentile is 15, and you 75th percentile is 31.

31 - 15 = 16.
