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. Therefore, Semi-Interquartile range = $\frac{Q_{3}-Q_{1}}{2}$. Where Q 1 and Q 3 are the upper and lower quartiles respectively.
The IQR is used to build box plots, simple graphical representations of a probability distribution. For a symmetric distribution (where the median equals the midhinge, the average of the first and third quartiles), half the IQR equals the median absolute deviation (MAD). The median is the corresponding measure of central tendency. The IQR can be used to identify outliers (see below). The quartile deviation or semi-interquartile range is defined as half the IQR. Algorithm. Quartiles are calculated recursively, by using median.
