Write a few sentences comparing the distributions of average English grade for light and heavy readers.

Do students who read more books for pleasure tend to earn higher grades in English? The boxplots show data from a simple random sample of 79 students at a large high school. Students were classified as light readers if they read fewer than 3 books for pleasure per year. Otherwise, they were classified as heavy readers. Each student’s average English grade for the previous two marking periods was converted to a GPA scale, where A = 4.0, A− = 3.7, B+ = 3.3 and so on.
