Overview for Power and Sample Size for 2-Level Factorial Design

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.

Where to find this analysis

To perform a power and sample size calculation for a 2-level factorial design, choose Stat > Power and Sample Size > 2-Level Factorial Design.
