Understanding Statistical Power for Non-Statisticians
Statistical power lays a foundation for a successful clinical trial, thus affecting all clinical trial professionals. Underpowered studies have a higher risk of not showing a statistically significant effect at the end of the study; whereas overpowered studies can lead to unreasonably large sample sizes, unnecessary risk to patients, and added expense. In this webinar, Dr. Usner addresses the basics of statistical power for non-statisticians, highlighting what you need to know about statistical power, how it affects your clinical trial, and what to ask for from your statistician.
