About this course

By the end of this course you should be able to:
understand why sample-size calculation is important prior to starting a study
recognise and understand the two different types of sample-size estimation - precision and power
understand the components required for sample-size calculation and how to estimate these
undertake sample-size calculation using the online excel sheets
adjust for unbalanced sample sizes in two groups
recognise and appropriately adjust for non-independent outcome measures

The course is open to anyone who wants to learn about the basics of estimating sample size.
Knowledge of the very basics of statistics (such as means, standard deviation, confidence intervals, etc.) is beneficial.

You can request a certificate of attendance for this course once you've completed it.

Course programme

You'll be introduced to the concepts of sample-size estimation, including when and why this might be necessary.

Formulae are presented and discussed. You'll be given online access to a series of excel sheets which are pre-programmed to allow you to use the formulae.

In the morning the precision-based approach to estimating sample size is introduced. The numbers are selected to produce a confidence interval for the relevant estimate with a specified width.

In the afternoon we progress to the more traditional power calculations which aim to give the sample required to determine a specified difference with selected power and significance levels.

All terminology will be explained as it's introduced in the sessions.

Sample-size estimation is discussed for the following measurements:

  • Means
  • Proportions/ percentages
  • Time-to-event data
  • Rates
  • Measures of agreement
  • Centiles
