3.3 The problem of selection for training in the HEI and the implementation of the state order

One of the main parameters of the distribution law and, especially, the normal distribution is the «average value of a random variable», for which the probability is greatest. In our case, it is a «score of EIE certificates» in the relevant subject, which is most often received by entrants in this group. Thus, for each of the above subsets has its own «average value of the scores of certificates of external independent evaluation», which determines the «polyhortality» of histograms, polygons and frequency distribution curves of this stochastic quantity. As an example, the scores of EIE certificates in mathematics in 2019 were analyzed (Fig. 3.23) [32].

The graphs obviously show a stratification of the entrant community. This is especially evident when comparing the graphs of the distribution of scores of external independent evaluation certificates in mathematics in 2008 (Fig. 3.22) and their distribution in 2019 (Fig. 3.23). For certificates in 2019, the hypothesis of a normal distribution law is not only confirmed, according to the Kolmogorov-Smirnov criterion, but in general the distribution graph loses the shape of the Gaussian curve.

Based on the calculations of the work [18], three subsets of the community of entrants are selected and their parameters are presented in the form of Table 3.9.
