WebThe factorial design, as well as simplifying the process and making research cheaper, allows many levels of analysis. As well as highlighting the relationships between variables, it also allows the effects of manipulating a single variable to be isolated and analyzed singly. WebThe total number of treatment combinations in any factorial design is equal to the product of the treatment levels of all factors or variables. Thus, in a 2 X 2 factorial design, there are four treatment combinations and in a 2 X 3 factorial design there are six treatment combinations. In more complex factorial designs, the same principle applies. WebFactorial designs are widely used by scientists, chemists and psychologists.
