- bretpiatt 4y agoThanks, missed the link, reading study. So many variables here including way the math portion was measured moving to multiple choice in the 1990s when the scores start dropping, hopping on a flight, still skeptical. Other quick one, all 95% confidence interval on data that moves less than +/- 2.5% either way. I understand confidence interval isn't a straight linear margin of error, it one I'd want to also look at further.
