The correlation coefficient between X and Y is r. Which of the following is correct? The correlation coefficient between X and Y is r. Which of the following is correct? If r is close to 1, the increase of X will always cause the increase of Y. If r is close to -1, the scatterplot of X and Y will be a random cloud of points. If r is close to 0, X and Y could show a strong non-linear relationship. A large value of r indicates that X and Y must have a strong linear relationship
