Detailed explanation-1: -To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
Detailed explanation-2: -Interquartile Range Formula The difference between the upper and lower quartile is known as the interquartile range. The formula for the interquartile range is given below. Interquartile range = Upper Quartile – Lower Quartile = Q3 – Q1. where Q1 is the first quartile and Q3 is the third quartile of the series.
