What Sample Size Do I Need?
|
Overview
Choosing an appropriate sample size is a common problem and should be given due consideration in any research proposal, as an inadequate sample size invariably leads to wasted resources. This course aims to give a practical introduction to sample size determination in the context of some commonly used significance tests. Examples from a scientific background will be used to highlight the problems associated with sample size determination, and suggest potential solutions. Practical work will be based around the statistical computing packages Minitab, R, SAS and Stata. The more specialised package PASS may also be used. Formulae and algebraic notation will be kept to a minimum. Who Should Attend? Scientists and related who need to address the problem of sample size determination in planning a study. Participants will be assumed to have a working knowledge of sampling distributions, confidence intervals and significance tests for both means and proportions. These materials are covered in our course A Review of Basic Statistics. How You Will Benefit This course will give you a sound introduction to sample size determination. Opportunity will be given to participants to discuss general issues related to sample size. What Do We Cover?
