In order to justify the effectiveness of the improved methodology based on 
the comprehensive design of the "English language" subjects of the recommended 
mathematical-statistical analysis of the final results, the results were analyzed 
based on K. Pearson's 
2
F
(xi-square) criterion and relevant conclusions were drawn 
[75]. 
In this case, we express the hypothesis
0
H
: there is no significant difference 
between the two samples, that is, the training of subjects of the "English language" 
in the control groups was not affected by the use of improved methodology based 
on the traditional teaching of English in the experimental groups.

alternative hypothesis: there is a significant difference between the 
samples, i.e., in the control groups, the study of "English" subjects in the 
experimental groups, as a result of the use of improved methodology based on the

traditional teaching of the English language, in the level of knowledge and mastery 
efficiency of students, in the formation of the skills of applying the acquired 
knowledge to educational practice and in their personal activities allows.
