(rank correlation and product-moment correlation) According to Cronbach, to the question “what is a good validity coefficient?” the only sensible answer is “the best you can get”, and it is unusual for a validity coefficient to rise above 0.60, though that is far from perfect prediction.

When calculating a correlation coefficient for ordinal data, select Spearman's technique. For interval or ratio-type data, use Pearson's technique. The value of a correlation coefficient can vary from minus one to plus one. A minus one indicates a perfect negative correlation, while a plus one indicates a perfect positive correlation.
