In the article the analysis of approaches to determine the distribution of the random variable and criteria for testing hypotheses in mathematical statistics. Proposed sensitive characteristics for estimation of the distribution law of random variables. Withdrawn two estimates delicate features, with which you can check the distribution of the random variables on the adequacy. The method (identification) of the law of distribution of parameters of quality of the processes of the quality management system as a random variable.
