Like the standard deviation, the interquartile range (IQR) is a descriptive statistic used to summarize the extent of the spread of your data. The IQR is the distance between the 1st quartile (25th percentile) and 3rd quartile (75th percentile). Q3 - Q1 = IQR.
The interquartile range, abbreviated IQR, is just the width of the box in the box-and-whisker plot. That is, IQR = Q3 â Q1. The IQR can be used as a measure of how spread-out the values are. Statistics assumes that your values are clustered around some central value. The IQR tells how spread out the middle values are; it can also be used to tell when some of the other values are too far from the central value.
