US Adult Obesity vs US Secondary School Enrollment
US Adult Obesity and US Secondary School Enrollment correlate at r = +0.61 over 27 years (1980–2022), p = 6.5e-4. With the time trend removed, r = -0.60. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.61, but once each series' time trend is removed it becomes -0.60. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
