Determining Sufficient Sample Size
September 13, 2011
Myra Kim
This workshop outlines how to calculate an appropriate sample size (n) to address the objectives of a research project. Participants will be led through essential steps for the design of a study: specifying the outcome variable, outlining hypothesis tests, estimating the variance or other "nuisance parameters," determining power to detect particular differences, and balancing these considerations against cost to arrive at a final sample size.
Participants have hands-on instruction in a computer classroom, using different sample size software such as nQuery Advisor or built-in sample size applications within Stata or SAS to compute sample sizes and plot power curves. Information on additional software is given. (This workshop does not cover survey research designs.)
- Course Content
- Sample size calculations to be covered include:
- comparisons of two means or proportions
- analysis of variance (ANOVA) designs
- repeated measures designs
- regression designs
- case-control study designs.
Special requests from those attending the workshop are welcome.
