Measurement and uncertainty for metrological applications. Repeated measurements and nested experiments1 Scope This Technical Specification follows the approach taken in the Guide to the expression of the uncertainty of measurement (GUM) and establishes the basic structure for stating and combining components of uncertainty. To this basic structure, it adds a statistical framework using the analysis of variance (ANOVA) for estimating individual components, particularly those classified as Type A evaluations of uncertainty, i. e. based on the use of
