      Correlation Coefficients Always Fall Between -1.00 and +1.00: A correlation coefficient of -1.00 tells you that there is a perfect negative relationship between the two variables.This means that as values on one variable increase there is a perfectly predictable decrease in values on the other variable.

      For this example, n=15 and with , we obtain a critical value of 0.946. Since the correlation coefficient (0.981) is larger than the critical value, we conclude in favor of the null hypothesis. We conclude that the errors are normally distributed. Modified Levene Test for Constant Variance (3.6) To conduct this test in EXCEL, do the following steps:

      The correlation coefficient is 0.942. Is this considered significant? Why or why not? No, because 0.942 is greater than the critical value of 0.707. Yes, because 0.942 is greater than the critical value of 0.707. No, because 0942 is greater than the critical value of 0.811. Yes, because 0.942 is greater than the critical value of 0.811.
