WebbUncertainty refers to epistemic situations involving imperfect or unknown information. It applies to predictions of future events, to physical measurements that are already made, or to the unknown. Uncertainty … WebbReply The uncertainty needs to be adjusted due to the dilution. Dilution by volume using a micropipette will usually have a standard uncertainty of around 0.5 % and dilution by weight a standard uncertainty 0.05 % (avoiding evaporation by e.g. delivering the liquid into a small testtube).

Webb6 nov. 2015 · 1. The uncertainty of a correction applied to a measurement result to compensate for a systematic effect is not the systematic error in the measurement result due to the effect. Rather, it is a measure of the uncertainty of the result due to incomplete knowledge of the required value of the correction.
