Do these two variables have positive correlation, negative correlation, or no correlation?
Answer
Positive correlation.

Example 9
Every day the weatherwoman predicts the high temperature for the day. Every day Loren records the high temperature of the day according to his thermometer. As far as Loren can tell, the weatherwoman's prediction has nothing to do with the actual high temperature for the day.
What are the two variables being discussed here? Do they have positive correlation, negative correlation, or no correlation?
Answer
The variables are the predicted high temperature and the actual high temperature. No correlation. That weatherwoman should lose her job. Even if her name is a delightfully perfect "Misty Spritz."
