The interquartile range (IQR), also called the midspread, middle 50%, fourth spread or H-spread, is a measure of statistical dispersion equal to the difference between the 75th and 25th percentiles of a data set, that is Q3 minus Q1. To compute it, a data set is divided into quartiles, four rank-ordered parts obtained by linear interpolation, and the IQR captures the spread of the central half of the data.
