    So, a set of data may be separated into quartiles, each quartile containing 1/4 (or 25%) of the data (hence the name quartile). The interquartile range (IQR) is the range that contains the middle half (50%) of the data.

    You know the definition of IQR. Apply that definition to this question and you'll have your answer.
