Group of answer choices

SSx = 2.75, SSy = 14.00, SP = 5.00, r = +0.81

SSx = 5.00, SSy = 13.00, SP = -6.00, r = -0.74

SSx = 2.75, SSy = 33.00, SP = -1.50, r = -0.16

SSx = 5.00, SSy = 18.00, SP = 9.00, r = +0.95

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
