5.3 Power for Subgroup Analysis

This lecture will be about power and sample size for subgroup analysis. We will discuss traditional and non-traditional ways to address power and sample size analysis when subgroup differences are present. Some questions to consider while completing this lesson include:

  • What is a subgroup analysis?
  • Why is subgroup analysis important?

Learning Objectives

  • Define subgroup analysis.
  • Demonstrate how to conduct power and sample size calculations for subgroup analysis.
