mælingarvöntun
Mælingarvöntun, or measurement uncertainty, refers to the doubt that exists about the result of any measurement. It is a fundamental concept in metrology, the science of measurement, and plays a crucial role in ensuring the reliability and comparability of measurement results. Uncertainty arises from various sources, including limitations in the measuring instrument, environmental conditions, the skill of the operator, and the method used for measurement.
Measurement uncertainty is not an error but rather a quantitative expression of the range within which the
In practice, uncertainty is evaluated through a process called uncertainty analysis, which involves identifying and quantifying
Standards such as ISO/IEC Guide 98-3 provide guidelines for expressing and evaluating measurement uncertainty. Proper consideration
