 The Experimental Design Assistant


A free resource from the NC3Rs used by over 5,000 researchers worldwide to help design robust experiments more likely to yield reliable and reproducible results.

The EDA helps you build a diagram representing your experimental plan, which can be critiqued by the system to provide bespoke feedback. The EDA also:

  • Recommends statistical analysis methods
  • Provides support for randomisation and blinding
  • Performs sample size calculations

For an overview of how the EDA works, watch our one minute video.

The EDA website also provides information about the different concepts of experimental design, and how to apply these in your experiments.
