How Many Runs Do I Need? Using Power and Precision to Size DOE's

presented by Shari Kraber

Learn how power calculations protect against factorial design being too small to detect important effects. Power, however, is not the appropriate tool to size mixture and response surface method (RSM) designs. To properly determine how many runs are needed to optimize products and processes, we advise using fraction of design space (FDS) to ensure good predictions across the design space. Discover the differences between these sizing tools and how to apply them to make the most of your experiments.
