Abstract:
|
Newcomers to factorial design find it difficult to choose appropriate designs with adequate power. During this luncheon, we will discuss a clear process to determine the best design that fits the problem. Attendees are welcome to bring their planning processes to share with the group. A discussion of statistical power will demonstrate how the size of the effect relative to the noise is a critical criterion in design selection. We also will discuss how to choose ranges for the input factors, the importance of evaluating aliases, and checking runs for safety. Various case studies will illustrate the importance of using a planning process to avoid DOE failure due to an incorrect design choice. Attendees will take away a variety of strategies for determining which factorial design is appropriate for their data analysis needs.
