Abstract

“How many subjects do I need for my study”? This is one of the most important (and frequently asked) questions a quantitative researcher needs to answer before conducting a study. A study with too few subjects (or participants) may fail to produce useful findings, whereas a study with too many subjects can waste time and resources.

If you conduct quantitative research or plan to do so in the future and want to learn more about how to make informed sample size decisions, please plan to attend this “lunch and learn” session.

Participants attending this session will learn:

- The role of effect size, alpha level, and statistical power in identifying the appropriate sample size
- Why the choice of statistical procedures can affect sample size requirements
- How to estimate target sample size for hypothetical scenarios through a practice exercise
