Correlation analysis uses the following steps.

1. Use Hypothesis Testing to decide if a significant relationship exists.
2. If there is a significant relationship:
   1. You need to decide if the relationship is meaningful.
   2. If the relationship is meaningful you need to use the coefficient of determination to decide how much of the variation in the dependent variable is accounted for in the variation in the variation of the independent variable.

Please answer the following questions.

1. What is a meaningful relationship?
2. How can a significant relationship not be meaningful?
3. What is the coefficient of determination?
4. What is the coefficient of non-determination?
