  • Cohen (1988) ("cohen1988"; default)

    • d < 0.05 - Very small

    • 0.15 <= d < 0.25 - Medium

    • d >= 0.25 - Large

Note

"Since g is so transparently clear a unit, it is expected that workers in any given substantive area of the behavioral sciences will very frequently be able to set relevant [effect size] values without the proposed conventions, or set up conventions of their own which are suited to their area of inquiry." - Cohen, 1988, page 147.
