US Solar Energy Consumption vs US Health Expenditure
US Solar Energy Consumption and US Health Expenditure correlate at r = +0.61 over 24 years (2000–2023), p = 0.0014. With the time trend removed, r = -0.61. 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 -0.61. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
