The Georgetown-Howard Universities Center for Clinical and Translational Science is delighted to sponsor and support a three-day power and sample size workshop. The short course, taught by Keith E. Muller, Ph.D., professor in the University of Florida College of Medicine, and Deborah H. Glueck, Ph.D., associate professor in the University of Colorado School of Public Health, will give scientists training for selecting a valid sample size for longitudinal and multilevel study designs. The workshop is accessible to all, from graduate students to senior researchers, and requires only basic statistical background.

Course Objectives:

  • Understand a framework and strategy for study planning
  • Write study aims as testable hypotheses
  • Describe a longitudinal and multilevel study design
  • Write a statistical analysis plan
  • Ensure sufficient sample size for subgroups for studies of disparities
  • Demonstrate the feasibility of recruitment
  • Describe expected missing data and dropout
  • Write a power and sample size analysis that is aligned with the planned statistical analysis
  • Write the design, analysis, power and sample size sections for a grant
