Sources of systematic error may be imperfect calibration of measurement instruments (zero error), changes in the environment which interfere with the measurement process and sometimes imperfect methods of observation can be either zero error or percentage error. If you consider an experimenter taking a reading of the time period of a pendulum swinging past a fiducial marker: If their stop-watch or timer starts with 1 second on the clock then all of their results will be off by 1 …
In metrology, measurement uncertainty is the expression of the statistical dispersion of the values attributed to a measured quantity. All measurements are subject to uncertainty and a measurement result is complete only when it is accompanied by a statement of the associated uncertainty, such as the standard … See more The purpose of measurement is to provide information about a quantity of interest – a measurand. For example, the measurand might be the size of a cylindrical feature, the volume of a vessel, the potential difference between … See more Sensitivity coefficients $${\displaystyle c_{1},\ldots ,c_{N}}$$ describe how the estimate $${\displaystyle y}$$ of $${\displaystyle Y}$$ would be influenced by small changes in the estimates $${\displaystyle x_{1},\ldots ,x_{N}}$$ of the input quantities See more The most common view of measurement uncertainty uses random variables as mathematical models for uncertain quantities and … See more The above discussion concerns the direct measurement of a quantity, which incidentally occurs rarely.
