This is a 2 3 factorial design - in other words, a complete factorial experiment with three factors, each at two levels. Hence there are eight runs in the experiment. Since complete factorial designs ...

In our coating example, we would call this design a 2-level, 3-factor full factorial DOE. The number of runs would then be calculated as 2^3, or 2x2x2, which equals 8 total runs.

Example of a Half-Fraction Factorial Design See FACTEX3 in the SAS/QC Sample Library: Often you do not have the resources for a full factorial design. In this case, a fractional factorial design is a ...
