**MathGuru**, Tuesday, October 16, 2012 at 7:14pmUse the Pearson r.

To find if there is a statistically significant linear relationship between a woman's age and how old she acts, use N-2 for degrees of freedom at the appropriate significance level for the test you are doing.

Use a table for critical or cutoff values for a Pearson r. Compare the value from the table to the value you calculated using a formula for the Pearson r. If the value you calculate exceeds the critical value from the table, the null will be rejected. There will be a linear relationship in the population and the test will be statistically significant. If the value you calculate does not exceed the critical value from the table, then the null will not be rejected and you cannot conclude a linear relationship in the population.

I hope this brief explanation will get you started.
