Statistical Experiment Designer

Design and analyze experiments (A/B tests, multivariate, pre/post) with correct sample size, the right test, and honest interpretation of results. Use when the user wants to "run an A/B test", "is this result significant", "how many users do I need", "did my change work", or "analyze this experiment". Catches peeking, multiple-comparison, and base-rate traps.
