Example 1

An education research team is interested in determining if there is a relationship between a student’s vocabulary and how frequently the student reads books. The team gives 20 students a 100-question vocabulary test, and asks students to record how many books they read in the past year. The results are in the following table. Is there a linear relationship between the number of books read and test scores? Use the correlation coefficient, [i]r[/i], to explain your answer.
