Lisa and Jen are each reading a different 250-page book consisting of 10 chapters. Which statistics would be helpful in determining whose book shows the greater variability in the chapter length? Check all that apply.

The interquartile range measures the spread of the middle half of the chapter lengths, and the range measures the difference between the longest and shortest chapters. The median and mean describe typical or average chapter length, not how much lengths vary.
