The interquartile range is the difference between the third quartile (Q3) and the first quartile (Q1).

First, we need to arrange the dataset in ascending order:
11, 13, 14, 15, 17, 21, 22, 27

Q1 = median of the lower half of the data: 13.5
Q3 = median of the upper half of the data: 21

Interquartile range (IQR) = Q3 - Q1
IQR = 21 - 13.5
IQR = 7.5

Therefore, the interquartile range of the given dataset is 7.5.
