Your question is Compare Pre-Post Behavior After Change. 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).
You work on a ride-sharing marketplace and a product change has just launched in the app. You want to understand whether customer behavior changed after the release, but simple before-and-after comparisons may be misleading because demand and seasonality also move over time.
How would you compare customer behavior before and after the product change, and how would you tell whether any observed difference is actually caused by the change rather than by time trends or other confounders?
