      Table I shows the values of the correlation coefficient that are significant for a specific level and a specific number of degrees of freedom. Any value of r greater than a positive critical value or less than a negative critical value will be significant, and the null hypothesis will be rejected.

      If your correlation coefficient is a larger negative number than the critical region, your data indicate a significant negative correlation. The closer your r-value is to —1.0, the stronger the negative correlation. REPORTING YOUR RESULTS. The examples below show how the results of your analysis of linear correlation should be presented.
