Graph description: Figure 13. Scatter diagram showing simulated data from a population where there is a perfect linear 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.

The points lie exactly on a straight line, falling from X = 3, Y = 5.5, to X = 7 and Y=3.5.

The correlation coefficient is r = -1.0.
