TABLE B.4: VALUES OF THE CORRELATION

COEFFICIENT NEEDED FOR REJECTION OF

THE NULL HYPOTHESIS

How to use this table:

1. Compute the value of the correlation coefficient.

2. Compare the value of the correlation coefficient with the critical value listed in this table.

3. If the obtained value is greater than the critical or tabled value, the null hypothesis (that the correlation coefficient is equal to 0) is not the most attractive explanation for any observed differences.

4. If the obtained value is less than the critical or tabled value, the null hypothesis is the most attractive explanation for any observed differences.
