Question

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

Explanation:

Step1: Identify Q1 and Q3

From the box plot, the lower quartile (Q1) is at 20 and the upper quartile (Q3) is at 60.

Step2: Calculate IQR

The interquartile range (IQR) is calculated as \( \text{IQR} = Q3 - Q1 \). Substituting the values, we get \( 60 - 20 = 40 \).

Answer:

40
