Step-by-Step Solution
No — this is observational. Correlation does not imply causation without a controlled experiment.
Key Tips from Pamela
- Only a randomized controlled experiment can establish causation.
- Observational studies show association, not cause-and-effect.
- Confounding variables are factors that could explain the relationship other than the variable being studied.
