Chapter 12, Problem 19CR

To determine

Find the box-and-whisker plot that represents the greater interquartile range.

Answer to Problem 19CR

box-and-whisker plot of $B$

Explanation of Solution

Given information:

Given:

  Calculation:

Here, we have:

  

Now, the interquartile range is defined as the length of the box or difference between third and the first quartile.

Thus, from the above graph we can observe that the length of box in $B$ is more wide than the length of box in $A$ .

Hence, box-and-whisker plot of $B$ is greater than the box-and-whisker plot of $A$ .
