To find the interquartile range, we first need to find the median (Q2) of the dataset, which is 16. We then split the dataset into two halves, with the lower half being {11, 13, 14, 15} and the upper half being {17, 21, 22, 27}.
Next, we find the median of the lower half (Q1), which is 13.5, and the median of the upper half (Q3), which is 19.5.
To find the interquartile range, we subtract Q1 from Q3:
19.5 - 13.5 = 6
Therefore, the interquartile range is 6.5.
