First factorial designs provide an additional control procedure â making a secondary. A design with 9 factors requires 512 runs. Doing a half-fraction quarter-fraction or eighth-fraction of a full factorial design greatly reduces costs and time needed for a designed experiment. Factorial design is now twice that of OFAT for equivalent power. Factorial designs allow additional factors to be examined at no additional cost.

Factorial designs are extremely useful to psychologists and field scientists as a preliminary study allowing them to judge whether there is a link between variables whilst reducing the possibility of experimental error and confounding variables. The relative efficiency of factorials continues to increase with every added factor. A completely randomized design that you proposed runs the risk of an unbalanced design and confounding factors making it difficult to determine the effect of the individual factors. Doing a half-fraction quarter-fraction or eighth-fraction of a full factorial design greatly reduces costs and time needed for a designed experiment.
