#### Research Methods Level 1

This class explains why we calculate sample size and how it can impact our research as chiropractors. Research is essential for chiropractors to test their theories, treatments, and manipulations. To verify that your manipulation/treatment works you will test it on patients, but how many patients are enough?

##### Learning Outcomes

- Understand concepts of sample size estimation and calculate power of a study with sample sizes provided in literature.
- Be able to calculate sample size based on your research question and outcome measures.
