The Biostats4you website was developed to serve medical and public health researchers and professionals who wish to learn more about biostatistics. The site contains carefully selected and vetted training materials especially suited for a non-statistician audience.

This site is being developed and maintained by members of the Biostatistics, Epidemiology and Research Design Special Interest Group (BERD SIG) of the Association for Clinical and Translational Science (ACTS).

Learning Objectives
Topics include:
  • Sample Size Calculators - Use these free online calculators to estimate the needed sample size for a straightforward one- or two-group study. 
  • Power and Sample Size Concepts - These resources explain the concepts of power and sample size and what they depend on.
  • Finding and Working with a Biostatistician - These resources provide guidance on how to find and work with a biostatistician. 
  • Data Collection and Management - These resources provide guidance on collecting and managing study data.  

We will be adding content to this site on an ongoing basis, so let us know if you have suggestions for additional topics! Please let us know if you have any problems using this site, or if you have suggestions for improving it. You can contact us at
