本研究旨在探討二項分配、波松分配與常態分配之間的關係，重新分析二項模式 在運動測驗上的實例，採科史適合度檢定，結果顯示：1.試做十次時，當成功機率為71.8% 資料僅適合二項分配，當成功機率為32.5%和成功機率為12.0%時，資料僅適合波松分配。 2.成功機率71.8%時不同試做次數的適合度檢定，試做次數為5、3、15時，資料僅適合二項 分配；試做次數為20、25時，資料僅適合波松分配。3.成功機率32.5%時不同試做次數的適 合度檢定，試做次數為25時，資料僅適合常態分配;試做次數為10時，資料僅適合波松分配 。4.成功機率12.0%時不同試做次數的適合度檢定，不同試做次數皆以適合波松分配為主。 得到結論為：本研究證實運動測驗適合模式的主要因素是試做次數和成功機率。

　　　　　The purpose of this study was to explore the relationship between Binomial, Normal and Poisson Distribution in the theory. Examples are given to illustrate the re-analysis of Binomial Model in psychomotor test. The approach was utilized for the Kolmogorov-smirnov goodness of fit test. The indication of the results were:1.In ten binomial trials, the success probability 71.8% was only fitted Binomial Distribution(BD), the probability of successes were 32.5% and 12% that only fitted Poisson Distribution (PD). 2.In success probability 71.8%, the trials were 5,10,15, that only fitted BD, the trials were 20 and 25 that only fitted PD. 3.In success probality 32.5%, the trials was 25 that only fitted Normal Distribution (ND), the trials was 10 that only fitted PD. 4. In success probability 12.0%, the difference of trials mainly fitted PD. In conclusion, this study provided the evidence that major factors of model fit are trial size and success probability in the psychomotor test.
