DR. CAROL SCENARIO: Dr. Carol conducts a study examining the relationship between exam performance, number of class absences, and amount of time spent studying in a large random sample. Below are her findings. Assume we are using .05 as our level of significance. Exam performance and number of class absences: r = −.67, p = .01 Exam performance and time spent studying: r = .31, p = .04 Number of class absences and time spent studying: r = .04, p = .66 Comparing all three correlations, Dr. Carol will be most able to accurately predict exam performance from the number of class absences because the relationship:
