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.

Almost all grant applications require a statistical power analysis. In this seminar, Todd Schwartz, DrPH, will explain the basics of what power analysis is, how it works, and how to conduct one.

Schwartz is a professor in the department of Biostatistics at the UNC Gillings School of Global Public Health. He works collaboratively with the UNC School of Nursing (joint faculty appointment), the UNC Thurston Arthritis Research Center (Co-Director of the NIAMS-funded Methodology Core) and the UNC Eshelman School of Pharmacy (adjunct faculty appointment). Much of his efforts are focused on supporting various projects across these units with regard to their biostatistical aspects, including consultation on design, conduct, analysis and dissemination. He also has published on innovative pedagogical methods, including the ‘flipped’ classroom.
