WebThe IQR is a measurement of the variability about the median. More specifically, the IQR tells us the range of the middle half of the data. Here is the IQR for these two distributions: Class A: IQR = Q3 – Q1 = 78.5 – 71 = 7.5 Class B: IQR = Q3 – Q1 = 89 – 61 = 28 As we observed earlier, Class A has less variability about its median. WebThe interquartile range (IQR) is therefore 18 - 4 = 14.
