Compare characteristics of standard response surface designs for four fac-

tors.

(a) Create a uniform precision central composite design, a Box-Behnken design, a small composite design, and a hybrid design.

(b) Compare the variance dispersion graphs or fraction of design space plots for each design, also compare the number of levels and total number of runs.

(c) Choose one of the designs you have created, export it to a .csv le to be used as a randomized data collection for the design.
