Question

What does it mean when the correlation coefficient has a positive value? A. When x increases, y decreases, and when x decreases, y increases. B. When x increases, y increases, and when x decreases, y decreases. C. When x increases, y decreases, and when x is constant, y equals zero. D. When x increases, y increases, and when x is constant, y decreases.

Answer 1

When the correlation coefficient has a positive value, this means that there is a positive slope. Slope is equal to rise over run or the change in y over the change in x. In this case, the answer should be B. . When xincreases, y increases, and when x decreases, y decreases.
