Which of the following is true about effect-size statistics?
A)A coefficient of determination that equals .09 signifies a trivial relationship.
B)The odds ratio is an effect-size statistic used in logistic regression with dichotomous data.
C)Eta is an effect-size statistic for two ratio-level variables.
D)An eta of .50 is weaker than a Cohen's d of .60

Question

Quizplus · Accepted Answer

The odds ratio is an effect-size statistic used in logistic regression with dichotomous data. A is incorrect because a coefficient of determination of .09 signifies a small, but not necessarily trivial, relationship. C is incorrect because Eta is an effect-size statistic for two nominal variables, not ratio-level variables. D is incorrect because an eta of .50 and a Cohen's d of .60 are both considered to indicate moderate effect sizes, but they cannot be directly compared as they measure different types of variables.
