onzekerheidsmeting
Onzekerheidsmeting, or uncertainty measurement, is a fundamental concept in metrology and scientific experimentation. It quantifies the doubt that exists in the measurement of a quantity. No measurement is perfectly exact; there will always be some degree of variability or deviation from the true value. Onzekerheidsmeting aims to express this deviation in a standardized and meaningful way.
The International Organization for Standardization (ISO) provides guidelines for expressing measurement uncertainty, most notably in the
There are generally two types of uncertainty contributions: Type A and Type B. Type A uncertainty is
The overall measurement uncertainty is usually expressed as a standard uncertainty, often denoted by 'u', which
