Your question is A/B Testing and Experimentation. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about your experience running A/B tests, including how you choose hypotheses, metrics, and sample sizes.
Explain your process from hypothesis formation through interpretation and launch decision. Use one representative experiment, or a clearly labeled illustrative example, and address randomization, primary and guardrail metrics, MDE, power, analysis timing, and common validity risks.
