Your question is Correlation vs Causation in Growth. 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 growth campaign and see that users exposed to it convert at a higher rate than users who were not. The team wants to know whether the campaign caused the lift or whether the pattern is just a correlation.
How would you explain the difference between correlation and causation in the context of a growth campaign?
