Do girls read more than boys during the summer? Serena’s class asked parents to estimate how many pages their child read over the summer. They collected the following data.  Homework Help ✎

Girls:   pages

Boys:   pages

  1. Make parallel box plots and compare the center, shape, spread, and outliers.

    What is similar about the two plots? What is different?

  2. Do girls read more? How many IQRs more do they read? Use the box plots to estimate.

    It cannot be determined that girls read more because the difference of pages is less than a fourth of the IQR.
