Your question is Correlation Versus Causation in Marketing. 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 are reviewing a marketing analysis and see that customers exposed to more campaign touches also show higher product adoption. You need to explain why that pattern alone does not prove the campaign caused the outcome.
How would you explain the difference between correlation and causation in a marketing analysis?
