To consult the statistician after an experiment is finished is often merely to ask him to conduct a post mortem examination. He can perhaps say what the experiment died of.

  1. An excellent observation. I’ve had too many people ask me for statistics help after the fact, and I’m not even an expert.

  2. This is so true. The worst is when a grad student comes to you and you realize that some experiments they designed for their thesis research were massively underpowered and/or poorly designed. It’s just so disheartening.
