Last year, the TraCS Biostatistics team hosted an introductory overview of power analyses. This talk is offered as a follow-up presentation, giving more varied information about sample size planning.
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. (Although the presenter 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 follow-up talk more difficult to follow.)
Presenter: Jeff Laux, PhD
Research Associate, NC TraCS Biostatistics
Format: ~1 hour talk, 30 min Q&A
The NC TraCS Biostatistics Seminar Series provides more in-depth discussion of select biostatistical topics for clinical and translational researchers who have basic quantitative training in biostatistical methods. Join us this fall for seminars on power analysis & sample size planning, parameter interpretation in generalized mixed regression models, basic steps in questionnaire development, and choosing the right graphs and tables for your data.
