The Range of Applying Approximate Methods of Expanded Uncertainty Estimation in Indirect Measurements

Przemyslaw Otomanski

Abstract

The results of examining error evaluation of the coverage factor with approximate methods in indirect measurements have been presented in the paper. Basing on the method?s accuracy analysis, the scope of application of the approximate methods of the expanded uncertainty estimation has been presented; the criterion of not-exceeding a preset value of the error has been implemented. The knowledge of coverage factor characteristics for the convolution of three selected probability distributions was used for the examination.
