Neat and brief preprint about design decisions that can improve statistical power, without increasing sample size. https://t.co/FtBCUDlAIL Summary: 1. Use fewer experimental groups 2. Focus hyothesis 3. Avoid discretizing continuos variables 4. Cross technical factors, don't nest
RT @deevybee: Nice preprint by Lazic on how changes to experimental design (as opposed to N) affect statistical power. https://t.co/tM7rD7X…
