WebMay 18, 2009 · The correlation coefficient can – by definition, that is, theoretically – assume any value in the interval between +1 and −1, including the end values +1 or −1. The following points are the accepted guidelines for interpreting the correlation coefficient: 1. 0 indicates no linear relationship. 2. WebFor example, correlations of .60 and -.60 are of equal magnitude, and are both larger than a correlation of .30. When there is no linear relationship, the correlation will be 0.00; when there is a perfect linear relationship (one-to-one correspondence between the values of the variables), the correlation will be 1.00 or -1.00.
