Question

A newspaper collected information on schools in its circulation area in order to compare their quality. Two measures the newspaper collected for each school, mean class size and mean score on a statewide reading exam, are shown in the scatterplot. A graph titled comparing schools has mean class size (students) on the x-axis, and mean state test score on the y-axis. Points decrease in a line with negative slope. Which statement regarding the association shown could explain the relationship? class size appears to have little effect on test scores. Schools in more affluent areas have larger class sizes, which is associated with higher test scores. Schools in more affluent areas have smaller class sizes, which is associated with higher test scores. Schools in less affluent areas tend to have smaller class sizes, which is associated with lower test scores.

Answer 1

The statement that could explain the relationship regarding the association  on the scatter plot is  (c) schools in more affluent areas have smaller class sizes, which is associated with higher test scores.

From the given scatter plot (see attachment), we have the following highlights

• The mean state score decreases as the mean class size increases
• The points are approximately linear, with a negative slope

The above highlights mean that:

The smaller the class size, the higher the test score.

Hence, the correct statement is (c)
