Your question is Statistical Evaluation of Campaigns. 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).
How would you assess the effectiveness of a marketing campaign using statistical methods?
Explain how you would define the outcome, establish a comparison group, select an appropriate statistical test, quantify uncertainty, and distinguish statistical significance from practical business impact. Address assumptions, potential bias, and how you would communicate the recommendation.
