In metrology, measurement uncertainty is the expression of the statistical dispersion of the values attributed to a quantity measured on an interval or ratio scale.
29 wrz 2010 · Learn what measurement uncertainty is, how to evaluate it, and how to express it using the GUM and related documents. Explore the Uncertainty Machine, a web application that demonstrates different methods of measurement uncertainty analysis.
Learn how to estimate measurement uncertainty for food microbiology testing and reporting according to ISO 19036 (2019). Find definitions, components, approaches, examples and requirements of the standard.
Learn the basics of measurement uncertainty, how to estimate and express it, and how to reduce it. This guide covers the concepts, methods, and examples of uncertainty of measurement, with references and links to further resources.
This document provides guidance on how to evaluate and communicate measurement uncertainty according to the Joint Committee for Guides in Metrology (JCGM). It covers the rationale, scope, parts and principles of the Guide to the Expression of Uncertainty in Measurement (GUM).
Measurement uncertainty is a parameter used in data processing for the description of both the dispersion of the result and its estimated difference from the accurate value. Frequently, this is simplified to only dispersion, and measurement uncertainty is obtained using statistical data variance.
Learn how to evaluate and express the uncertainty of measurement results using the method adopted by NIST and ISO. Find basic definitions, examples, and references for further information.
