A)before the variability due to individual differences has been removed B)after the variability due to individual differences has been added C)after the variance has been divided by df D)after variability due to individual differences has been removed

Question

Quizplus · Accepted Answer

In a correlated-groups t test, the independent variable is usually the condition or treatment to which participants are exposed. Therefore, eta² represents the proportion of variability in the dependent variable (i.e., the outcome of interest) that is associated with the independent variable (i.e., the condition or treatment) after variability due to individual differences has been removed. This is important because it allows researchers to focus on the specific effects of the independent variable on the dependent variable, without being confounded by individual differences that might distort the results.
