D) It is always better for detecting curvilinear relationships than are simple designs.

A factorial design involves manipulating two or more independent variables simultaneously and examining their effects on the dependent variable. In a factorial design, all levels of each independent variable are combined with all levels of the other independent variable(s). This allows for the examination of main effects (the influence of a single independent variable on the dependent variable) and interactions (the combined effect of two or more independent variables on the dependent variable). It does not necessarily eliminate the possibility of a confound, and a control group may still be necessary depending on the specific research question. Finally, factorial designs are not inherently better for detecting curvilinear relationships than simple designs.
