🟢 Repeat: P-Value Check
Without looking, answer: "Your A/B test got p = 0.08 at α = 0.05. A stakeholder asks if the feature works. What do you say?"
Answer: "We don't have sufficient statistical evidence at our pre-set 5% significance level to conclude the feature has an effect. This doesn't mean there's NO effect — it means our sample may not be large enough to detect it. We could run the test longer or consider if the minimum detectable effect was set appropriately."
