Raj polled 100 students in his class to compare the number of hours that teen boys and girls played video games each week. The results of his survey are shown here. Which gender shows greater variability in their playing time?

To compare variability in box plots, compare the interquartile ranges (IQRs), which measure the spread of the middle half of the data. The girls’ IQR is 12 hours, while the boys’ IQR is 8 hours, so the girls’ playing times show greater variability. The median and skew alone do not measure the spread this comparison asks about.
