US Coal Consumption vs US Adult Obesity
US Coal Consumption and US Adult Obesity correlate at r = -0.32 over 45 years (1980–2024), p = 0.031. With the time trend removed, r = +0.85. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.32, but once each series' time trend is removed it becomes 0.85. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
