What Sample Size do I need? With Stata

Cass Business School 1 day (11th February 2020 - 11th February 2020) Stata Intermediate, Introductory
Delivered by: James Gallagher & Sandro Leidi (Statistical Services Centre Ltd)


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 gives a practical introduction to sample size determination in the context of some commonly used statistical hypothesis tests.

Examples from a scientific background will be used to highlight the problems associated with sample size determination and suggest potential solutions. Delegates will have the opportunity to discuss general issues related to sample size.

Course Agenda

Day 1

The course will cover the following:

  • Concept of significance and power in relation to hypothesis tests
  • Sample size determination for one sample, two samples and paired samples for both t-tests (means) and z-tests (proportions)
  • Practical problems associated with sample size determination and possible solutions
  • The role of confidence intervals
  • Why it can be difficult to determine sample size
