I previously talked about measurements (some) when I looked at the uncertainty in the distance to the Sun. One of the simple ways of determining the uncertainty of a calculated quantity is to use the ...

Bayesian uncertainty analysis represents a powerful statistical framework that integrates prior knowledge with observed measurement data to quantify uncertainty in a consistent probabilistic manner.

Accuracy is a desirable aspect which is conceptually well defined. There are some definitions available for ‘accurate measurement’ in the ISO vocabulary of metrology terms. According to them, a ...

The technique which is recommended by the regulatory bodies ISO (International Organisation for Standardisation) and BIPM (Bureau International des Poids et Mesures) is one of the most comprehensive ...

What is the meaning of Heisenberg’s analogy? (Courtesy: German Federal Archives) A row has broken out among physicists over an analogy used by Werner Heisenberg in 1927 to make sense of his famous ...

Evaluation of accuracy (trueness) in a normal environment includes the three errors of sensitivity, linearity, and eccentricity, and the acceptance criterion, 0.10%, according to the error propagation ...

A reliable assessment of measurement uncertainty in calibration services is an essential qualitative requirement for any calibration laboratory. While general guidance on the estimation of measurement ...
