How to setup an a/b test to compare 2 different user interfaces
Explain how you would design and analyze the experiment end to end. Cover the hypothesis, primary metric, guardrails, minimum detectable effect, sample-size calculation, randomization unit, duration, statistical analysis, and ship or do-not-ship criteria. State any assumptions explicitly, and address peeking, novelty effects, sample ratio mismatch, and potential violations of SUTVA.
