Interpreting Box Plot IQR

The video tutorial explains how to determine which box plot has the greatest interquartile range (IQR) by analyzing four different box plots labeled A, B, C, and D. The IQR is calculated by subtracting the first quartile (Q1) from the third quartile (Q3). Box Plot A has an IQR of 12, Box Plot B has an IQR of 14, Box Plot C has an IQR of 10, and Box Plot D has the greatest IQR of 16. The tutorial provides a step-by-step analysis of each box plot to determine the IQR and concludes that Box Plot D has the largest IQR.

What is the main objective of the problem discussed in the video?

• To identify the box plot with the most outliers

• To determine which box plot has the greatest IQR

• To find the box plot with the smallest range

• To compare the mean values of different box plots

How is the IQR calculated for Box Plot A?

• By adding Q1 and Q3

• By dividing Q3 by Q1

• By subtracting Q1 from Q3

• By multiplying Q1 and Q3
