A researcher would like to know whether there is a consistent, predictable relationship between ACT scores and GPA for high school students. A sample of 100 students is obtained from students who took the ACT in their Junior year. Based on the test results and gpa scores, students are classified as high or low for ACT and for GPA. The results are summarized in the following frequency distribution: ACT Score High GPA Low GPA High 39 15 Low 21 25 Based on the data, is there a significant relationship between ACT scores and GPA (a = .05). Compute the appropriate measure of association.
