关于测验题目的聚类分析

THE CLUSTER ANALYSIS OF TEST ITEMS

本文应用多元分析及统计方法,对测验题目提出了两种新的相似性量度,分别阐述了从题目关于能力目标的聚类和知识内容的聚类。它比单以相关系数作为相似性量度的聚类有更确切的意义.并以一九八四年理科高考数学试题为例,用其中一种方法作了聚类分析。

By applying multivariate analysis and statistics method,the author puts forward two new similarity measures for test questions and gives descriptions of questions with regard to clusters of ability object and knownledge content respectively.The new methods show themselves more exact in significance than the method taking unitary related coefficient for similarity measure cluster.The mathematical questions of the college entrance examination of 1984 was analysed by applying one of the new method as an example.
