Explanation:

Step1: Identify Q1 and Q3

In a box - plot, the left - hand side of the box is Q1 and the right - hand side of the box is Q3. From the box - plot, Q1 = 50 and Q3 = 150.

Step2: Calculate the IQR

The inter - quartile range (IQR) is calculated as IQR=Q3 - Q1. Substitute Q1 = 50 and Q3 = 150 into the formula: IQR = 150−50.
