The technique of processing and evaluating uncertainty of results of parallel measurements is stated. For processing results of parallel measurements the method of reduction is used. Сoverage factor for a case of two parallel measurements by a method of Monte Carlo and through effective number of degrees of freedom are designed, differences in the received results are analysed. The example evaluating uncertainty of results of tests of spread of concrete mix is considered.
