Quizplus · Accepted Answer

Nullifying a score means removing the influence of the independent variable on the dependent variable. This is usually done in experimental designs to isolate the effect of a particular treatment or intervention. A nullified score represents the dependent variable score after the influence of the independent variable has been accounted for. A and B are incorrect as adding or subtracting a unit from each score does not nullify the effect of the independent variable. D is incorrect as the unexplained variance refers to the variability that is not accounted for in a group, which is not the same as nullifying a score.
