The interquartile range (IQR) helps measure the variability of a dataset by indicating the range of the middle 50%. To find it, first find the median (Q2) of your data set, then find the median of the lower half (Q1) and upper half (Q3). Subtract Q1 from Q3 (IQR = Q3 - Q1). It helps to spot outliers and understand data spread. Have you tried calculating the IQR for a specific data set? What challenges are you facing with it?
