Chapter 11: Q.23 (page 695)

Do students who read more books for pleasure tend to earn higher grades in English? The boxplots below show data from a simple random sample of 79students at a large high school. Students were classified as light readers if they read fewer than 3books 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 where4.0=A,3.0=B and so on.

Reading and grades (1.3) Write a few sentences comparing the distributions of English grades for light and heavy readers.

Short Answer

Expert verified

The centre of light readers is lower than that of heavy readers, and the distribution of light readers is more spread out than that of heavy readers, as seen in the graph.

Step by step solution

01

Step-1 Given Information

Given in the question that, the figure is:

we have to Write a few sentences comparing the distributions of English grades for light and heavy readers.

02

Step-2: Explanation

The center of light readers is lower than that of heavy readers, and the distribution of light readers is more spread out than that of heavy readers, as seen in the graph. The median of the box plots also appears to be symmetric, indicating that the distribution is symmetric.
