The Significance of the Correlation Coefficient
When r is not 0, then you either have a significant linear relationship or you do not. To determine if you have a significant linear relationship you need to perform a statistical test. Steps
1. State the hypotheses
2. Find the critical r value
3. Compare your r value to the critical r value
4. Make a decision
