Data considerations for Define Custom General Full Factorial Design

Consider the following guidelines when you define the design.

The size of the design should be adequate
The sample size and power should be desirable for a practically important effect size. To evaluate the design, use Stat > Power and Sample Size > General Full Factorial Design.
The design should have 2 to 15 factors
If you have only one factor, you can use One-Way ANOVA without defining the design.
The run order should be randomized for data collection
If the worksheet contains a column that contains the run order, you can specify that column when you define the design. Otherwise, you can randomize the design after you define the design with Stat > DOE > Modify Design.
