WebIn many factorial designs, one of the independent variables is a nonmanipulated independent variable. The researcher measures it but does not manipulate it. The study by Schnall and colleagues is a good example. One independent variable was disgust, which the researchers manipulated by testing participants in a clean room or a messy room. WebFactorial design simplifies the research process and is cost-effective in nature. Factorial design highlights the relationships and causality between variables.
