Interquartile Range (IQR): How to Find and Use It
https://statisticsbyjim.com/basics/interquartile-range/
WEBThe formula for finding the interquartile range takes the third quartile value and subtracts the first quartile value. IQR = Q3 – Q1. Equivalently, the interquartile range is the region between the 75th and 25th percentile (75 – 25 = 50% of the data). Using the IQR formula, we need to find the values for Q3 and Q1.
