Question

Use the linear correlation coefficient given to determine the coefficient of determination, r².

r = -0.71

a. r ² = -50.41%

b. r ² = 50.41%

c. r ² = 84.26%

d. r ² = -84.26%

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
