# 2^3-1 factorial design

## Consider the two-level, full factorial design for three factors, namely the 23 design. This implies eight runs (not counting replications or center point runs). Graphically, we can represent the 23 design by the cube shown in Figure 3.1. The arrows show the direction of increase of the factors.

Construction of a 2 3-1 half fraction design by staring with a 2 2 full factorial design: First note that, mathematically, 2 3-1 = 2 2. This gives us the first step, which is to start with a regular 2 2 full factorial design.

How to design a mixed factor fractional factorial… Do we have nowadays the software which can design a mixed factor fractional factorial experiment? Probably in R, Matlab, Unscrambler? I have 2 factors with level 2 and 3 factors with level 3. The full factorial experiment 2^2 3^3 = 108 runs, but I want to reduce it to 54. Someone knows how to do it? Social Research Methods - Knowledge Base - Factorial … Factorial Design Variations. Here, we'll look at a number of different factorial designs. We'll begin with a two-factor design where one of the factors has more than two levels.Notice that in this design we have 2x2x3=12 groups! Although it's tempting in factorial studies to add more factors, the... Design of Experiments – Full Factorial Designs |… In designs where there are multiple factors, all with a discrete group of level settings, the full enumeration of all combinations of factor levels is referred toTo create the full factorial design for an experiment with three factors with 3, 2, and 3 levels respectively the following code would be used
