Problem

How did you validate your design decisions?

Answer this as a practical experimentation question. Explain how you would validate the hypothesis, primary metric, guardrails, MDE, sample-size assumptions, unit of randomization, and analysis plan. Discuss how you would detect invalid results, including peeking, sample ratio mismatch, novelty effects, or a mismatch between randomization and analysis units.
