Web1 Jul 2000 · possible. Systematic erroris the result of a mis-calibrated device, or a measuring technique which always makes the measured value larger (or smaller) than the "true" value. An example would be using a steel ruler at liquid nitrogen temperature to measure the length of a rod. The ruler will contract at low temperatures Webfor completeness, there's also a simple equation for addition/subtraction like x = a + b - c (sx)^2 = (sa)^2 + (sb)^2 + (sc)^2 again where s is the error of the measured varaibles a b and c. Constants without measurement error are simply carried through. Share Cite Improve this answer Follow answered Apr 22, 2024 at 21:42 rrr 232 1 2 9
