Question

the box plot below represents some data set. what is the interquartile range (iqr) of the data?

Explanation:

Step1: Identify Q1 and Q3

In a box - plot, the left - hand side of the box represents the first quartile (Q1) and the right - hand side of the box represents the third quartile (Q3). From the box - plot, Q1 is approximately 20 and Q3 is approximately 30.

Step2: Calculate the IQR

The inter - quartile range (IQR) is calculated as IQR = Q3 - Q1. Substituting the values of Q1 and Q3, we get IQR=30 - 20.
