Advanced topic: In a factorial analysis of variance,the effect size for each main and interaction effect
A)is the same for each effect.
B)is the same number for row and column effects,but different for the interaction effect.
C)is different for each row,column,and interaction effect.
D)cannot be calculated because only an effect size for the overall combination of main and interaction effects can be calculated.

Question

Quizplus · Accepted Answer

In a factorial analysis of variance, the effect size is different for each row, column, and interaction effect. This is because each effect has its own unique variability and impact on the outcome, and therefore must be evaluated separately. It is not the same for each effect, as in choice A, nor is it the same number for row and column effects but different for the interaction effect, as in choice B. It is also possible to calculate effect size for each individual effect, not just the overall combination, making choice D incorrect.
