Suppose the available resource is enough for conducting 8 runs. 24 full fac-torial design consists of all the 16 level combinations of the four factors. We need to choose half of them.

4.1 Two Factor Factorial Designs A two-factor factorial design is an experimental design in which data is collected for all possible combinations of the levels of the two factors of interest.

Executive Summary ng point for the design phase of testing. A full factorial design is a simple systematic design style that allows for es imation of main effects and interactions. This design is very useful, but …

The most common approach is the factorial design, in which each level of one independent variable is combined with each level of the others to create all possible conditions.

The F-test for the “model” source is testing the significance of the overall model; that is, is either A, B, or AB or some combination of these effects important? Alternatively, use Minitab‟s DOE functions ...

The parameter estimates obtained in the manner for the factorial design with all factors at two levels (− and +) turn out to be least squares estimates (more on this later).
