Your question is Evaluate a New Marketing Initiative. 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 marketing team that wants to launch a new initiative and compare it against the current approach. Leadership wants to know whether the change actually improves performance before rolling it out more broadly.
How would you apply statistical analysis to evaluate whether the new marketing initiative is better than the current one? Walk through how you would define success, size the test, and decide whether the result is strong enough to ship.
