WebA 2 × 2 factorial design has four conditions, a 3 × 2 factorial design has six conditions, a 4 × 5 factorial design would have 20 conditions, and so on. Figure 8.1 Factorial Design Table Representing a 2 × 2 Factorial Design. In principle, factorial designs can include any number of independent variables with any number of levels. WebFactorial designs can address more than one question in one study in an elegant manner and significantly reduce the required sample size. In general, an n-factor study decreases the required sample size by a factor of n. So a two-factor study (e.g., 2 × 2, 3 × 3, or 4 × 4) requires half the number of patients that running two separate studies would need.
