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