With the number of observations n, the known probability distribution describing the sample median for n-2 observations was used to approximate the uncertainty of the population median. The proposed approximation was tested by comparison with exact results for n  ≤  10 and with the Monte Carlo method. It has been shown that the standard and expanded (confidence level p = 0.90, 0.95, and 0.99) uncertainties determined by the proposed approximation differ from values determined by MCM by less than about 1%. Using the median instead of the mean value as the measurement result provides a measurement uncertainty lower by about 25% when n ≥ 35, and over 29% when n ≥ 70.}, title={Simple and accurate method to evaluate type a standard and expanded uncertainties of measurement for the Laplace distributed observations}, type={Article}, URL={http://czasopisma.pan.pl/Content/134227/06_2k.pdf}, doi={10.24425/mms.2024.152049}, keywords={uncertainty of measurement, population, Laplace, median, distribution, approximation}, }
