Interpret Cohen's g

Description

Interpret Cohen's g

Usage

interpret_cohens_g(g, rules = "cohen1988", ...)

Arguments

g	Value or vector of effect size values.
rules	Can be "cohen1988" (default) or a custom set of rules().
...	Not directly used.

Rules

Rules apply to equally to positive and negative g (i.e., they are given as absolute values).

• Cohen (1988) ("cohen1988"; default)

  • d < 0.05 - Very small

  • 0.05 <= d < 0.15 - 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.
