Your question is Conflicting Experiment Results. 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).
What would you do if an experiment showed conflicting results across segments?
Explain how you would determine whether the differences reflect a real treatment interaction, random variation, data-quality problems, or aggregation effects. Define the primary metric, guardrails, minimum detectable effect, unit of randomization, and analysis plan you would require before interpreting segments. Address sample-ratio mismatch, multiple comparisons, peeking, Simpson's paradox, and how you would make a ship, don't-ship, or follow-up decision.
