CALCULATION OF EXPANDED UNCERTAINTY

Jerzy M. Korczynski, Andrzej Hetman
  • Abstract:
    The main purpose of the paper is to present a method of calculation of the expanded uncertainty at required confidence level. It is elaborated as a piece of software with the main intention for metrology and quality engineering courses. The definition based algorithm is used and convolutions of different probability density distribution are precisely calculated. The uniform, triangular, normal and t-Student distributions are implemented in the software. One of the advantage is no limitation of encountered measurands.
