Results of comparison of values of coverage factor for a composition of the t-distribution with uniform, normal and arcsine laws of distributions received by a Monte-Carlo simulation and by means of effective number of steppes of freedom are analyzed. A technique of obtaining of the expanded uncertainty and the coverage factor in view of the laws of distribution of contributions of uncertainty of type B without use of a Monte-Carlo simulation are considered.
Keywords: the expanded uncertainty in measurement, coverage factor, Monte-Carlo simulation, t- factor, effective degrees of freedom
