Studies in physical education take up study based on superiority, mostly. These problem was often made some results on a be signified nothing, for the reason being similar to the effect on existing treatment method, despite existing economic, timely and environmental profit. if some treatment is profit from economic, timely, environmental and etc point of view, researcher should be performed study on equivalence and nor-inferiority. Therefore, we introduced method and procedure testing equivalence and non-inferiority between two treatments., shine than, we explained on method of analyzing data and interpreting the results, applying virtual data. Finally, we expect that equivalence and non-inferiority test are used in various aspect of physical education.

The purpose of this study were to find out meaning, suitable, difference among models that applied some method of paired comparison analysis for estimating abilities of each of KBL teams. For this purpose, scoring records and match days in 2015~2016 season were collected from KBL Web-site. And it were analyzed by Bradley-Terry model, general linear model using difference of scoring between two teams and Dynamic Bradley-Terry model. Analyzed results were compared with real order of each team in 2015~2016 season. All data were analyzed by r-program x64(3.3.0). Conclusively, Paired comparison analysis can estimate consistent abilities regardless of opposite teams. In addition, general linear model using difference of scoring between two teams can use to consider to effectiveness of scoring and Dynamic Bradley-Terry model can apply on figure out the main factor about changing abilities.

In results, Main factors and patterns related victory were ; 1. Korean player`s game has 8 factors(AST, FTA, P2, WFT, WOFT, FT, FTA, BS) and 15 patterns. On the other hand half korean player`s game has 7 factors(TL, WFT, OFF, FT, BS, P2, P3) and 9 patterns. 2. Korean players match patterns and factor analysis of the game. The node pattern is AST 2.5 over→ P2 0.5 over→ WFT 0.5 over→ FTA 2.5 over. 3. Game pattern and factor analysis of Half korean`s games. The node pattern is STL 1.5 over→ WFT 1.5 under→ FT 5.5 over→ FTA 2.5over.

This study, in order to report on the current status of training for national Taekwondo athletes classified by continent, questionnaires were distributed to 129 athletes who participated in the 2007 World Taekwondo Championship, and consequently analyzed. SPSS WIN 12.0 program was used for statistical processing of collected data, in which frequency analysis was used The results show that the first time that the athletes started Taekwondo, classified by continent, is during the time of elementary school, and as for the motive for starting the sport, asking by parents and relatives was the highest. Usual training period per day was about 4 hours max. only for Oceania and Europe, while for the rest of the group, it was about 5 hours max.
