Rasch模式分析2012年國際高爾夫LPGA的選手成績

Rasch Analysis of Golfer's Scores for LPGA Taiwan Championship 2012 in Taiwan

利用試題反應理論單參數的Rasch模式，分析2012年國際女子高爾夫(LPGA)台灣錦標賽的選手成績及其揚昇球場：(1)18洞標準杆之設定是否適當；(2) 18洞是否符合單向度的預期；與(3)製作網路KIDMAP的選手成績之診斷，提供選手未來LPGA比賽之決策參考。結果發現，揚昇球場18洞標準杆之設定尚稱合理；75位選手第一天18洞的效度檢測內聚均方誤介於0.5與1.5間，符合杆數加總單向度測量的要求；網路KIDMAP診斷分析圖，可以提供選手4天72洞之成績改善的訊息，即刻檢測出哪一天哪一球洞的不合理異常特徵。網路KIDMAP診斷分析，可以對高爾夫錦標賽的選手自我評估，提供一個示範分析的途徑；對於國際高爾夫比賽的客觀測量與分析，也提供未來發展上的借鏡與參考。

In order to effectively help contestants examine their scores in golf competitions, we demonstrated assessing psychometric properties of their scores for LPGA Taiwan Championship 2012 in Taiwan on (1) whether each hole of setting par is appropriate, (2) whether 18 holes for a unidimensional test is of validation, and (3) whether KIDMAP is a self-assessing report card for individual contestants. We adopted Rasch analysis with Winsteps computer software to examine all of the 72 holes for the 75 golfers in the 4-day 4-round competition held in Taiwan from October 25 to 28 in 2012. The measurement of LPGA 2012 had a moderate reliability coefficient of 0.59 for all contestants. The contest for the Sunrise court in one day first round on 18 holes can be unidimensional. Each par hole setting for LPGA 2012 is appropriate. KIDMAP diagnosis can provide golfers with an objective and sufficient examination to identify their scores on 72 holes in a golf competition. A newly-innovated KIDMAP diagram of self-assessment might be an effective screening approach used for LPGA golfers in the future.
