The results of the appropriate statistical analysis can be found below.    The three variables involved in this study are listed below. Next to each variable, indicate whether each variable is a predictor or criterion variable.

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 In determining whether the relationship between two of Dr. Carol’s variables was statistically significant, which of the following must be considered?
