Example text

A€negative relationship, sometimes called an inverse relationship, occurs when scores on variable X increase (from left to right) as scores on variable Y decrease (from top to bottom). 3 (b) and (e) are examples of negative relationships. There is no relationship between X and Y when for a large value of X, a large or a small value of Y can occur, and for a small value of X, a large or a small value of Y can also occur. 3 (c). The strength of the relationship among X and Y is determined by the scatter of the points (hence the name scatterplot).
