But error analysis in the real world may use different terms in different fields. For example, in engineering it was common to use the concepts of "systematic error" & "random error". "Systematic error" is a predictable offset between the measured value and the true value which you can remove by calibration, while "random error" is unpredictable and cannot be calibrated. Meanwhile, BIPM's Guide to the Expression of Uncertainty in Measurement (GUM) uses a different system to define "Type 1/2" uncertainty. | |
