THE UNCERTAIN NUMBER: A DATA MODEL FOR MEASUREMENT

• Abstract:

  A simple model for data obtained by measurement is described. The data model satisfies requirements for evaluation and reporting of measurement uncertainty given in the Guide to the expression of uncertainty in measurement (GUM). The model supports what is called internally consistent and transferable calculations, which are qualities favoured by the GUM. In this way, more rigorous GUM-compliant digital data processing can be supported than the common reporting format of a single value for measurement uncertainty presently allows.
