9.1 Introduction. Factorial treatment designs are necessary for estimating factor interactions and offer additional advantages (Chapter 6).However, their implementation is challenging if we consider many factors or factors with many levels, because the number of treatments then might require prohibitive experiment sizes.

The simplest factorial design is the 2 × 2 factorial with two levels of factor A crossed with two levels of factor B to yield four treatment combinations. A special case of the 2 × 2 factorial with a placebo and an active formulation of factor A crossed with a placebo and an active formulation of factor B. This yields the four treatment regimens:

This design structure is represented as a 2 × 2 (two by two) factorial design because there are two factors, and each factor has two levels. This four-celled structure is considered the simplest factorial design (Mee 2009). In a 2 × 2 factorial design, both factors have the ability to be manipulated or held as a constant.

Basic Elements of RCT and Factorial Designs. In an RCT an "active" treatment arm or condition is statistically contrasted with a "control" treatment arm or condition (Friedman, Furberg, & Demets, 2010).The two conditions should be identical except that the control condition lacks one or more ICs or features that are provided to the active condition.

A factorial design with (t) factors is identified using the (l_{1} l_{2} ldots l_{t}) notation, where (l_{i}) is the number of levels of factor (i) ((i=1,2, ldots,t)). For example, a factorial design with 2 factors A and B, where A has 4 levels and B has 3 levels, will have the (4 times 3) notation. ...
