A parameter characterizing dispersion of quantity values reasonably attributable to a chemical measurand under a stated model.

This is an authored directed relation from the source endpoint to the target endpoint.
Chemical measurement uncertainty adds chemistry-specific contributions such as sampling, preparation, matrix effects, species definition, calibration, and metrological traceability to the general evaluation framework.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.

Under an explicit measurement model, a probability distribution can represent knowledge about a chemical measurand; this does not identify uncertainty with repeatability, instrument resolution, or a population frequency.
A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.
wp-probability-distributionnlab-probability-distributionwp-chem-analytical-chemistryiupac-orange-bookThis is an authored directed relation from the source endpoint to the target endpoint.
A quantitative result is qualified by uncertainty for a defined measurand and coverage statement, incorporating identified calibration, sampling, preparation, model, repeatability, and other contributions.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
