The main difference of two strategies lies in grade 3 and the grade 4 and there is no difference in the grade land the grade 2; there is the obvious positive correlation between sex and the experimental design, and there isnt obvious correlation between sex and the elementary knowledge; the Spearman rank correlation coefficient r_s=

梯度指导策略与突击强化策略的教学效果的主要区别在于梯度3、梯度4的得分，在梯度1、梯度2上基本无差异；性别与实验设计有明显的正相关，性别与基础知识无明显的正相关；生物基础知识与实验设计成绩的Spearman等级相关系数，r_s=0.443，0.4＜r_s＜0.6，即学生的生物基础知识与实验设计成绩呈中等正相关。

In this paper,with respect to the ordinal variables,the definitions of attribute reduction of dominance-based rough set approach in ordered information systems and ordered decision tables are given.Then the approach of sorting objects comprehensively using rough set theory is brought in to obtain a series of ranks.Based on these ranks,nonparametric methods to analyze correlation between two attribute subsets are introduced,and Spearman rank correlation coefficient is used as a measure of attribute correlation.Based on this measure,a new method of attribute reduction of ordered information systems and ordered decision tables is presented without changing the ordinal information of the universe.
