The importance of experimental units 

This video from the British Pharmacological Society explains the importance of experimental units and how these need to be correctly identified for good experimental design.
Robust experimental design underpins the success of drug discovery. In an in vivo setting it is fundamental to ensuring animal welfare and achieving the 3Rs (replacement, reduction and refinement).
