US Dollar to British Pound vs US Mobile Subscriptions
US Dollar to British Pound and US Mobile Subscriptions correlate at r = +0.50 over 26 years (1999–2024), p = 0.0092. With the time trend removed, r = -0.74. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.50, but once each series' time trend is removed it becomes -0.74. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
