Weak, negative relationship: As the variable on the x-axis increases, the variable on the y-axis decreases. The dots are fairly spread out, which indicates a weak relationship. Pearson correlation coefficient: –0.46 WebA positive association is when the line on the graph is moving upward, like in Problem 1. You see, the line is moving up. Therefore, it is a positive association. In Problem 2, the line is moving down. That is called a negative association. No association is like in Problem 3, when there isn't a clear line at all.
