选择题测验不可靠性的统计模型及分析

The Statistical Modelling and Analysis of Multiple-choice and True/False Tests' Uncertainties

首先分析了在单项选择题测验和多项选择题测验中由于猜测题目答案所引起的测验分数的不可靠性 ,并给出了统计模型。然后讨论了两种测量不可靠性的方法 。

Test unreliability due to guessing in multiple choice and true/false tests is analysed, and two measures are described: the resolution of defined levels of knowledge and the probability of examinees being incorrectly ranked. At last several relevant questions are also discussed.
