Conditions of sporting level of fencers at master stage of training

The paper presents complementary set of statistical methods (factor analysis, taxonomic analysis, one of so called aggregate methods, analysis of information store), leading to separation of a set of variables bringing the greatest stockpile of information on the sporting level of athletes practicing fencing. Especially worth emphasizing is the application and verification of the method (index of competitive development), enabling linear sorting of investigated objects (athletes practicing fencing). Such solution creates conditions of methodologically correct application of strong statistical methods (linear regression function) of great importance in sport prediction.
