Jeff Laux, PhD
Last year we hosted an introductory overview of power analyses. This talk is conceived as a follow-up presentation, giving more, and more varied, information about sample size planning. Although I will provide a brief review of hypothesis testing and the basics of power at the beginning, people who are wholly unaware of power analysis may find this talk harder to follow. Emphasis will be given to different kinds of sample size estimation for different situations, the notion of effect size and how to estimate it, and some strategies to improve power. Audience: clinical investigators Technical level: beginner Registration: https://apps2.research.unc.edu/events/index.cfm?event=events.go&key=B3EE This event is being cross-promoted by the NC BERD Consortium, a collaboration of the CTSA-funded BERD cores at UNC-Chapel Hill, Wake Forest University, and Duke University.
