Study design: effect sizes and statistical analyses

A video from Professor Hazel Inskip (University of Southampton) discussing the key considerations when determining the effect size for a study, and why this is so important, including for determining sample size.

This presentation originally formed part of the NC3Rs May 2018 workshop on experimental design for panel members of the NC3Rs, BBSRC, CRUK, MRC and Wellcome Trust.
