November 22, 2022 | 12:00 pm - 1:00 pm
The HMH Research Institute presents Biostatistics Education Series Part 2: Sample Size Determination.
Themba Nyirenda, Ph.D., Research Biostatistician,
Office of Research Administration
Contact Tamara Friedman, Ph.D. for Zoom information.
This lecture will cover determining sample size and conducting power analyses for estimation and testing problems, respectively. Various research problems with appropriately selected designs will be presented and discussed from inception to preparatory inputs (effect size, minimum clinically important difference) with a focus on the sample size calculation step and actual computation of the samples using R software. The lecture will also highlight the role of confidence level, margin of error, Type I error (significance level), and Type II. The Power of test in each of the designs that will be discussed.
Target Audience: Physicians, scientists, nurses, and any other team members who may be involved or interested in research.
