Use Power and Sample Size for 2-Level Factorial Design
to examine the relationship between power, number of replicates, effect size, and the number of center points. Use these calculations for the following reasons:
- Before you collect data for a designed experiment to ensure that your design has enough replicates to achieve acceptable power.
- After a designed experiment, to evaluate whether the designed experiment needed more experimental runs.
