To my understanding, Hedges's g is a somewhat more accurate version of Cohen's d (with pooled SD) in that we add a correction factor for small sample.

For all practical purposes, unless you're dealing with really small sample sizes, it probably doesn't matter which you use (although if you can pick, you may as well use the one that I've called Hedges' g, as it is unbiased).īorenstein, M., Hedges, L. They are all virtually identical if $n > 20$ or so, and all can be interpreted in the same way. If someone says "unbiased Cohen's d", you're just going to have to take your best guess at either of the last two (and I think there might even be another approximation that has been used for Hedge's $g^*$ too!). People seem to refer to any of these three estimators as Hedge's g or Cohen's d interchangeably, although I've never seen someone write " $g^*$" in a non-methodology/stats research paper. 27)īut, as for what people mean when they say Cohen's d vs. (Originally from Hedges, 1981, this version from Borenstein, Hedges, Higgins, & Rothstein, 2011, p.

Hedges' $g^*$ (the computationally trivial approximation): However, this correction factor is fairly computationally complex, so Hedges also provided a computationally trivial approximation that, while still slightly biased, is fine for almost all conceivable purposes: (originally Hedges 1981, this version developed from Hedges and Olkin 1985, p. Where $df = n_1 + n_2 -2$ for an independent groups design, and $\Gamma$ is the gamma function. Where $s$ is the pooled standard deviation,
