8. 9. 9), can be chosen. The selection of the larger design is then made to allow a given statistical interpretation of the effects (see further). When the number of factors to be examined is lower than the number of factors that potentially can be examined in a PB design (N − 1), the remaining columns are defined as so-called dummy factors. A dummy factor is an imaginary variable and changing its levels does not correspond to any physical or chemical change. Therefore, its estimated effect can be considered as a measure for experimental error and used in the statistical evaluation of the estimated factor effects (see further).

For example, to examine three factors, a three-level full factorial design requires 33 = 27 experiments and a CCD of at least 15, while two-level screening designs with eight (FF or PB) or, theoretically, even four experiments (FF) (7) can be chosen. Moreover, during screening, usually (much) more than three factors are evaluated. Using three-level screening designs, such as reflected designs, up to seven factors can be examined in 15 experiments. Now, when more than three factors are examined, the number of experiments increases dramatically when response surface designs would be used.

Occasionally, an FCCD is used. In the latter design, the factors are varied at only three levels (−1, 0, +1). To obtain a so-called rotatable circumscribed CCD, the levels of the star 14 design (−α, +α) should fulfill the requirement α = ( 2 f ) . Then all experiments, except the center point, are situated on a circle or (hyper)sphere. 83, for 2, 3, 4, 5, and 6 factors, respectively (7). As mentioned above, the center point is often replicated to evaluate experimental precision. In general, usually 3–5 center point replicates are performed.
