Proper rounding of the measurement results under normality assumptions

Year: 2000

Type: article

Abstract: We introduce a new method for rounding of measured values and their uncertainties. We define a new concept called `ε-properly rounding' and describe exactly the probability properties of the rounded measured values and their `ε-proper confidence intervals'. We propose general rules for proper rounding of the measurement results under normality assumptions. Finally we examine the probabilistic properties of the standard methods of rounding given in the Guide to the Expression of Uncertainty in Measurement of the ISO (1995).
