- Definition: Interquartile range is the measure of dispersion which is the difference in the values of two quartiles. The Lower Quartile is denoted as Q 1 and the Upper Quartile is denoted as Q 3. The interquartile range is Q 3 - Q 1. Semi Interquartile range is the midpoint of the interquartile range. In other words, it is one-half of the difference between the third quartile and the first quartile.

How Are Outliers Determined in Statistics? The interquartile range is what we can use to determine if an extreme value is indeed an outlier. The interquartile range is based upon part of the five number summary of a data set, namely the first quartile and the third quartile. The calculation of the interquartile range involves a single arithmetic operation.
