模糊統計常用來解決人類多元複雜的曖昧與不確定的現象，而本研究則嘗試利用模糊理論來進行學習成就測驗中的標準設定。在測驗領域，書籤標定法為一種最常用的方法。然而，標準設定成員常面臨無法找出一個明確的切點來放置書籤位置，而在兩或三個書籤切點中徘徊猶豫，進而影響到標準設定成員們共識的形成。本研究旨在將模糊理論融入在傳統的書籤標定法中，並用來找出最佳的切斷分數。實徵研究之結果顯示，模糊書籤標定法有其使用上的優點，尤其在成員決定切斷分數時，比傳統的書籤標定法更容易形成共識。

Fuzzy bookmark method has some promising features that help resolving theunclear thinking in human logic and recognition, in this paper, the author use fuzzystatistical analysis technique and a novel modified bookmark procedure to find anoptimal cutoff score. Empirical study shows that our proposed fuzzy bookmarkprocedure has the advantages in finding an appropriate standing setting than theconventional one. The comparison results of these two procedures are also presentedand discussed.
