This lecture is about graphics for power and sample size. We will talk about power curves, how to choose a graphic that tells the desired story, and look into different inputs that affect power. Some questions to consider while completing this lesson include:
- What is the relationship between intracluster correlation and power?
- What is the relationship between cluster size and power?
- Describe power curves.
- Decide how to choose a graphic that best tells the desired story.
- Describe how design inputs affect power.
