Scenario
Management wants to measure how negative customer reviews affect the repurchase rate of a coupon.
Task
Design an analysis to quantify the causal impact of negative reviews on the probability that a user repurchases the same coupon. Specify:
- The outcome, treatment, unit of analysis, and time windows.
- The data you would need (including exposure to reviews).
- A modeling and/or causal inference approach that isolates the review effect from confounders (e.g., matched cohorts, fixed effects, difference-in-differences, propensity scoring).
