A supplement to the eta squared effect size is
A) gamma squared.
B) omega squared.
C) delta squared.
D) zeta squared.

Question

Quizplus · Accepted Answer

The best choice is B as the supplement to eta squared effect size is omega squared, which takes into account both systematic and error variance, unlike eta squared which only considers systematic variance. Choice A (gamma squared) is not a supplement to eta squared, but another effect size index that may be used in ANOVA. Choices C (delta squared) and D (zeta squared) are not commonly used effect size indices.
