Level Of Difficulty And Beauty Expression Event Groups Competition Scoring In Assessment Of Closed System Research

In this paper, using the method of literature, mathematical statistics,logic analysis, to understand the subjective score concept, understand theessence and purpose of subjective scoring.On the influence of subjectivegrading judge justice factors were summed up and.From the angle ofEuclidean distance parameter selection, correlation coefficient, standarddeviation of three mathematical models respectively, the accuracy,validity, stability is evaluated from the perspective of non parameter;selection of centrifugal distance, Kendall Concord coefficient calculationof the referee's evaluation of individual objectivity, relevanceevaluation.The five evaluation index by using the progressive scoremethod, according to the weights of the evaluation level of objectivity ofevaluation.Parameter test and non parametric test two kinds of assessmentmodels combined, can make two kinds of methods deficiency was mutualsupplement and perfect, comprehensive evaluation more scientific, theevaluation more reasonable and objective.In order to validate the feasibility and practicability of the evaluationsystem, to the2010National Cheerleading Championship and theNational Cheerleading League Division final result data according to thecase analysis. Study results showed that: first, the concept of subjectivegrading to be defined as: to determine the competition ranking refereesaccording to the specific competition rules, by subjective and objectiveevaluation of two different indicators measured on the comprehensiveevaluation of sports ability. Second, affect the difficulty and beautyexpression event groups race referee impartiality subjective gradingfactors include: characteristics of difficulty and beauty expression event-group sports competition itself athletes or sports teams factors of referee's own factors other factors. Third, through to the score level comprehensiveevaluation, scored according to the value of the size, can be thetournament referee levels were high ranking, artistic judges score levelsare high to low ranking: No.2, No.1, No.4, No.3; completed the judgelevel rank:2,1no, No.3, No.4. On the level of scoring in rank to rank,facilitates selection of outstanding referee, referee for the next gameselection, provide the basis for optimization of implementation.
