B.) proportion of variability in the DV attributable to the IV.

C.) estimated standard error of prediction based on the IV.

D.) proportion of variability in the IV that is not due to subject differences.

(Behavioral Statistics)

Answer 1

solution::-

Eta-squared reflects the " PROPORTION OF VARIABILITY IN THE DV ATTRIBUTABLE TO THE IV "

OPTION " B " is correct answer.

Eta-squared measures the proportion of variance in dependent variable in which it is associated with the membership of different groups defined by a independent variable.

since Eta-squared is a measure of the effect size in ANOVA table.

In which the proportion of variability can be caluclated by dividing the SS(TREATMENT) by SS (TOTAL).

So option "B" is correct answer
