Quizplus · Accepted Answer

To examine main effects in an experiment with multiple independent variables (IVs), researchers often collapse across the levels of other IVs, effectively ignoring the specific conditions of those other IVs to focus on the effect of one IV at a time. This process allows for the analysis of each IV's individual contribution to the dependent variable.
