WebAccording to Cohen (1988, 1992), the effect size is low if the value of r varies around 0.1, medium if r varies around 0.3, and large if r varies more than 0.5. The Pearson correlation is computed using the following formula: Where. r = correlation coefficient. N = number of pairs of scores. ∑xy = sum of the products of paired scores.
