This course explores foundational research concepts and values within the context of physical therapy research and practice. While the course aims to assist examinees in preparation for a board certification exam, all practicing clinicians will be able to apply this information to interpret effect sizes, reliability, and likelihood ratios in order to make decisions about their clinical practice. At the end of the course, participants will be able to read these values in a research report and analyze how useful the test or finding will be in practice.
Learning Objectives
- Analyze how p values and alpha levels affect the likelihood of type I and type II errors in physical therapy research
- Determine an intervention’s effectiveness using effect sizes reported in a research article
- Determine the reliability and clinical utility of a test using a Cohen’s kappa value reported in a research article
- Use likelihood ratios to determine whether a clinical finding should result in a small or large shift in the probability of an outcome
