Correct answer: c. Confounds interfered with measuring your dependent variable or manipulating your independent variable.

Why? Error Variance

Error variance refers to changes in the dependent variable resulting from unwanted factors, such as subject boredom or room lighting, because these factors have nothing to do with the measure under study in the experiment. The degree of influence of some ...
