Hello. I do language education research, and in a recently submitted study used multiple linear regression (MLR). The study falls under the area of industrial-organizational psychology research, or applied psychology more broadly. A reviewer asked me to report F2, and I did so, using Cohen's f2 as a measure of effect size of the MLRs in the study. In doing so, I used the ranges I could find online, stating that f2 of 0.02 indicates a small effect, 0.15 a medium effect, and 0.35 a large effect. However, in the next round of the reviews, I was reminded of the criticism against Cohen's ranges and was asked to use a field specific one. I've searched diligently and found a lot of information for reporting Cohen's r or d, but I can't find a guide for interpreting Cohen's f2 in applied psychology or I-O psychology research. Does anyone know a convention for interpreting f2 in these areas? Any references you could share in this regard would be most welcome.
thank you for the interesting question but it is not my matter because I am focused on behaviorism more than the statistical matter
Here is a good starting point: imaging.mrc-cbu.cam.ac.uk. Notice, in this article Cohen's f for different effect sizes using multiple regression are different than what you cite.
this research cites many studies that are relatively recent and quite informative.
