WebPhi is related to the point-biserial correlation coefficient and Cohen's d and estimates the extent of the relationship between two variables (2×2). The phi coefficient can also be expressed using only , , , and , as = (). Maximum values. Although computationally the Pearson correlation coefficient reduces to the phi coefficient in the 2×2 ... WebThe Cohen’s d effect size is immensely popular in psychology. However, its interpretation is not straightforward and researchers often use general guidelines, such as small (0.2), …
