Graph description: Figure 11. Scatter diagram showing simulated data from a population where there is a weak negative relationship between the variables

A scatter diagram.

The horizontal axis is labeled "Variable X" and numbered 2, 4, 6, and 8. The vertical axis is labeled "Variable Y" and numbered 2, 4, 6, and 8. Each of the 50 observations is shown by a small diamond positioned at that subject's Variable X and Variable Y.

There is a relationship between X and Y. When X is small, Y tends to be large. When X is large, Y tends to be small.

When X = 3, Y ranges from = 4.5 to 6.5. When X = 7, Y ranges from = 3 to 5.

The correlation coefficient is r = -0.3.
