While researching a topic, a student has taken the following notes:
- A 2022 study analyzed geotagged social media posts to assess the effect of parks on happiness in 25 US cities.
- The happiness benefit of a city's parks was the numeric difference between the calculated happiness scores of posts made in parks and posts made elsewhere.
- A benefit above 0 indicates a positive effect.
- The park happiness benefit in San Francisco, California, was greater than 0.10.
- The park happiness benefit in Washington, DC, was greater than 0 but less than 0.10.
- The average happiness benefit of parks across all cities was 0.10.
