Biostatistics Seminar Series: Power analysis and sample size planning

In last year’s NC TraCS Biostatistics Seminar Series, we held an introductory overview of power analyses and sample size. This year's Power analysis and sample size planning seminar is a continuation on the topic of statistical power that provides more, and more varied, information about sample size planning.

In this seminar, Jeff Laux, PhD, will provide a brief review of hypothesis testing and the basics of power. 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. Please note: This seminar will be most helpful to those who have some knowledge of power and sample size.

The NC TraCS Biostatistics Seminar Series helps clinical and translational researchers collaborate more effectively with consulting biostatisticians by building deeper understanding of key statistical concepts and methods. Researchers then are better able to (1) evaluate relevance of the concept or method for research aim(s) definition and choice of study design; and (2) properly interpret the results of data analysis.
