But the real gem? The . It’s a spreadsheet from hell where every instrument, every human reader, every tape measure thermal expansion gets an error term. Sum them properly (root-sum-square, not absolute — that’s the rookie mistake), and you get the truth: We are 95% confident that the true value lies within ±2.3% of what we measured.
