碩士 === 國立體育大學 === 競技與教練科學研究所 === 105 === The purpose of this study is to analyze the skills of women's doubles players during matches by Rasch measurement. The subjects were Wu and Chiang, a pair of women’s doubles from the national team. There are two steps of methods. First, record the tournament on site. Second, observe and analyze based on the statistics from the scorers. The tournament skills were separated into seven stages, including early serving stage, middle serving stage, late serving stages, early receiving stage, middle receiving stage, late receiving stage, and rally. There are three results of this study. First, from the players’ perspective, the Rasch reliability scale is 0.87 with homogeneity and normality test. This indicates that the actual measurement is effective with sample representation. Second, from the scorers’ perspective, there is a consistency of scores from five scorers with homogeneity. Both the information-weighted mean-square fit statistic and the outlier sensitive mean-square fit statistic fit this model. It also indicates that the scores are appropriate for Rasch measurement. Third, from the skill perspective, the Rasch reliability scale is 0.93. Homogeneity and normality test prove that the estimation is effective with sample representation. The conclusion is that multi-stages of Rasch measurement quantify the performance of badminton doubles games, as well as analyze the potential of the overall match and the ability of seven-stages match skills.
