In a box - plot, the left - hand side of the box is the first quartile (Q1) and the right - hand side of the box is the third quartile (Q3). Here, Q1 = 5 and Q3 = 12.

Step2: Calculate the interquartile range (IQR)

The formula for the interquartile range is IQR=Q3 - Q1. Substitute Q1 = 5 and Q3 = 12 into the formula: IQR=12 - 5.
