Factorial Design Example Problems. For example with three factors the factorial design requires only 8 runs in the form of a cube versus 16 for an OFAT experiment with equivalent power. Because the generator set I ABCE ADEF BCDF contains only four letter words this is classified as a Resolution IV design.
This experiment is an example of a 2 2 or 22 factorial experiment so named because it considers two levels the base for each of two factors the power or superscript or levels factors producing 2 2 4 factorial points. 1 6 b 0. Introduction to 2K Factorial Design of Experiments DOE Formula Equation Explained with Examples.
In the example there were two factors and two levels which gave a 2 2 factorial design.
If k number of variablesfactors are studied to determinescreen the important ones the total. Cube plot for factorial design. For example with three factors the factorial design requires only 8 runs in the form of a cube versus 16 for an OFAT experiment with equivalent power. First we consider an example to understand the utility of factorial experiments.
