WebOct 18, 2016 · These effect sizes, like f^2 (which is a transformation of R^2), and r (the correlation) are designed to help interpretation when you don't know what else you're doing. A correlation of 0.1 is a small correlation. But a correlation of 0.01, in a regression with one predictor, leads to an f^2 of 0.01. But an f^2 of 0.02 is a small effect size.
