US Internet Usage vs US Secondary School Enrollment
US Internet Usage and US Secondary School Enrollment correlate at r = +0.70 over 19 years (1990–2022), p = 8.3e-4. With the time trend removed, r = -0.35. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.70, but once each series' time trend is removed it becomes -0.35. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
