Correlation The Pearson correlation coefficient, r. Correlation is perfect when r = ( 1, strong when r is greater than 0.8 in size, and weak when r is less than 0.5 in size. ( More correlation The three common pitfalls when interpreting a correlation coefficient involve causality, linearity and significance.

The significance test for a Pearson correlation coefficient is not robust to violations of the independence assumption. If this assumption is violated, the correlation significance test should not be computed. SPSS© computes the Pearson correlation coefficient, an index of effect size. The index ranges in value from -1.00 to +1.00.

of relationship is a straight line or linear relationship which is measured by the Pearson correlation (or the relationship between 2 variables). The . strength . or consistency of the relationship is measured by the numerical value of the correlation. A value of 1.00 indicates a perfect relationship and a value of zero indicates no relationship.
