Modeling uncertainty
Web26 okt. 2024 · Quoting your uncertainty in the units of the original measurement – for example, 1.2 ± 0.1 g or 3.4 ± 0.2 cm – gives the “absolute” uncertainty. In other words, it explicitly tells you the amount by which the original measurement could be incorrect. The relative uncertainty gives the uncertainty as a percentage of the original value.
