改良T-scoreとその評点表

概要

論文の詳細を見る
To compare the marks which are derived from different problems tests, hitherto we have used frequently T-score corresponding to their marks. But in this paper we show that the T'-score which is determined by the next expression is more desirable than the usual T-score. 〓 In this expression A denotes the mark in case that a full mark is marked on hundred points, and q=1-P, P=P/100, and P denotes the avarage mark. Lastly we add the table of T'-scores for various values of P and A.
