Web— Measurement uncertainty 2 OIE Validation Guidelines 2014 The variation of the results for control samples can also be used as an estimate of those combined sources of uncertainty and is called the “top-down” approach. This approach recognises that the components of precision will be manifest in the ultimate measurement. Web(c) measurement uncertainty relates to the degree of verifiability. The Conceptual Framework explains that verifiability helps assure users that information faithfully represents what it purports to represent, so measurement uncertainty should be considered as a factor that affects whether economic phenomena can be faithfully represented. 22.
