Abstract

The purpose of this study was to analyze records of Korean pro-basketball using general linear model (two-way ANOVA and hierarchical multiple regression analysis). Korea Basketball League (KBL) informed the records (2014-2015 season) of this study. The eight variables (TA, 2PA, 3PA, 2P, 3P, Ast, TFB, CH) were selected in content validity. SPSS program was used to analyze general linear model. All alpha level was set at 0.05. Major results were as follow. 3PA had significant interaction effect between victory & defeat variable and home & away variable. Victory teams showed that 3PA was higher in home games than away games, and defeat teams was the other. 2PA, AS, TFB, and CH were selected significant variables affecting victory and defeat. In result of hierarchical regression, Ast had significant moderation effect between 3PA and TS. TFB also had significant moderation effect between AS between 2P. The other construct (Ast between 2PA and TS; TFB between AS between 3P) had no significant moderation effect. In the effect of 2PA, 3PA and Ast to TS, CH also had no significant moderation effect.

이 연구는 일반선형모형에 이원변량분석과 위계적회귀분석을 적용하여 한국남자프로농구 경기기록 (2014-2015 정규리그 270경기)을 분석하였다. 이원변량분석 결과, 3점슛시도에서 승패와 홈원정 집단간에 상호작용효과가 통계적으로 유의하게 나타났다. 이 외에 변인들 (2점슛시도, 어시스트, 속공, 선수교체)은 모두 승패 집단간에는 통계적으로 유의한 차이가 나타났고, 홈원정경기 간에는 유의한 차이가 없게 나타났다. 위계적회귀분석 결과, 어시스트는 3점슛시도가 총득점에 미치는 영향에 대해 통계적으로 유의한 조절변수로 나타났으며, 속공은 어시스트가 2점슛성공에 미치는 영향에 대해 유의한 조절변수로 나타났다. 반면 어시스트는 2점슛시도가 총득점에 미치는 영향에, 그리고 속공은 어시스트가 3점슛성공에 미치는 영향에 유의한 조절효과가 없는 것으로 나타났다. 마지막으로 선수교체는 2점슛시도, 3점슛시도 그리고 어시스트가 총득점에 미치는 영향에 통계적으로 유의한 조절효과가 없는 것으로 나타났다.
