What is the uncertainty factor?


Distribution of GMO results showing approximately lognormal distribution

Appropriate expression of the measurement uncertainty (MU) is crucial, and there are situations when the traditional, symmetric, expanded uncertainty interval is not sufficient. This leaflet aims to explain the concept of the uncertainty factor and how it can be used to provide a convenient and realistic uncertainty interval in particular circumstances..

This leaflet was produced by the Eurachem Sampling Uncertainty Working Group and the Royal Society of Chemistry Analytical Methods Committee (AMC) Sampling Uncertainty Working Groups.
