基于粗糙集的试卷分析

Analyss of Test Papers Based on Rough Set

数理统计法无法判断试题是否冗余,也无法算出试题的重要程度。为此,运用粗糙集理论对试卷进行分析,揭示隐藏其中的冗余信息和重要度信息。主要的价值在于找出试卷分析的一种新方法,并实例说明分析的过程。

Mathematical statistics can＇t judge whether a test question is redundant or not,and so compute significant level For improving, applying rough set theory, analyses the test paper, and discovers both redundance and significant level information. The great value it made is that the novel way to analyse test papers is discovered, the course of analysis is explained by the example.
