Your question is Handling Conflicting Experiment Metrics. 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 your experiment results show a significant increase in one metric but a significant decrease in another?
Explain how you would determine whether the result supports shipping, iteration, or stopping the experiment. Address metric hierarchy, practical significance, statistical validity, pre-registered decision rules, and possible causes such as novelty, segmentation, or instrumentation issues. State what additional information you would request before making a recommendation.
