Question

For the following values of SS_X, SS_Y, and SP, the Pearson correlation coefficient (r) is ______ and the slope of the regression line (b) is _______.

SS_X	SS_Y	SP
50	80	50

r = -0.79, b = -1.00

r = 0.79, b = 1.00

r = -1.00, b = -0.79

r = 1.00, b = 0.79

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.
