Question

Quizplus · Accepted Answer

A main effect of factor B exists if, on average, the levels of factor B have different effects on the dependent variable, regardless of the levels of factor A. This question does not provide specific data or context, but the concept of a main effect does not depend on the levels of another factor (in this case, A), hence the answer is "yes" if we are to assume B has different effects across its levels.
