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. WebAug 19, 2010 · For very small sample sizes (<20) choose Hedges’ g over Cohen’s d. For sample sizes >20, the results for both statistics are roughly equivalent. Both Cohen’s d and Hedges g has same interpretation: Small effect (cannot be discerned by the naked eye) = 0.2. Medium Effect = 0.5.
