Web for example, with two factors each taking two levels, a factorial experiment would have four treatment combinations in total, and is usually called a 2×2 factorial design. Web an example and resources are described for using a two by two factorial design in simulation research. The number of digits tells you how many independent variables (ivs) there are in an experiment, while the value of each number tells you how many levels there are for each independent. In a 2 × 2 factorial design, both factors have the ability to be manipulated or held as a constant. Researchers often use factorial designs to understand the causal influences behind the effects they are interested in improving.
It looks almost the same as the randomized block design model only now we are including an interaction term: Formulas for degrees of freedom. Web chapter 6 of bhh (2nd ed) discusses fractional factorial designs. An experiment with only 8 runs is a 1/4th (quarter) fraction.
