Example Scatter Diagrams
In reading scatter diagrams, we can often draw useful conclusions just from the appearance of the scatter plot. Here are some examples:
 |
Positive Correlation. An increase in X will result in a relatively predictable increase in Y |
 |
Some positive correlation. An increase in X will result in a relatively unpredictable increase in Y |
 |
No correlation |
 |
Some negative correlation. An increase in X will result in a relatively unpredictable decrease in Y |
 |
Negative correlation. An increase in X will result in a relatively predictable decrease in Y. |
