Everything a product manager needs to know about experiments
A vocabulary checklist for experimentation. I disagree that every PM needs a stats identity, and I still want the words for bias, power, and stopping rules.
Why I saved this
Experiments 101 is a map, not a religion. I keep it because teams skip stopping rules and call a one-week dip a pivot. The craft is designing a decision, not collecting p-values as trophies.
Mind the Product has the original. This is the argument I actually use.
