Your choice for inner and outer arrays depends on the number and type of factors you have. Selecting a Design for Eight Signal Factors shows the available inner array choices when you have eight signal factors. If you also have noise factors, choices include designs for the outer array. To follow along, enter eight two-level Signal factors and click Continue. Then highlight the design you want and again click Continue. This example uses the L12 design.

If you did not specify a noise factor, after you click Continue, a dialog appears that asks you to specify how many times you want to perform each inner array run. Specify two (2) for this example.
