For central composite designs, it is not uncommon for the data to be collected in blocks owing to the size of the experiment. The advantage of using either the central composite or box behnken designs to generate response surfaces is that fewer experiments are required. They can be less expensive to do than central composite designs with the same number of factors. 2 k factorial & central composite designs.
