Allows you to select a design, add center points and replicates, and block the design.

Dialog box items

The list box at the top of the Design subdialog box shows all available designs for the number of factors you selected in the main Create Factorial Design dialog box. Highlight your design choice. The design you choose will affect the possible choices for the options below.

Number of center points per block: Choose the number of center points to be added per block to the design. When you have both text and numeric factors, there really is no true center to the design. In this case, center points are called pseudo-center points. See Adding center points for a discussion of how Minitab handles center points.

Number of replicates for corner points: Choose the number of replicates.

Number of blocks: Choose the number of blocks you want (optional). Click the arrow for the number of blocks to see a list of possible choices. This list contains all the possible blocking combinations for the selected design with the number of specified replicates. If you change the design or the number of replicates, this list will reflect the new set of possibilities.
