In 1988 Cohen suggested the following interpretation for effect size: "small~0.20, Medium~0.50, Large~0.80". I'm aware that these values are rather arbitrary and that an extensive disclaimer in this respect is already in Cohen's work.
Yet, is there a similar interpretation for Cliff's delta?
I found something similar for Cramer's V Small 0.1 0.2, Medium 0.3 0.5, Large 0.5. But nothing about Cliff's delta.
