## Practice and review

Synthetic data: treatment moves 20% to 28%; comparison moves 18% to 23%. The raw change is eight points; DiD is (28−20)−(23−18)=three points. A causal interpretation needs credible assumptions, and statistical significance is not established by this arithmetic.

- [ ] Percentage points and percent changes are distinct.
- [ ] Correlation, adoption and prediction are not presented as causation.
- [ ] Unmet targets and shared conditions are disclosed.
