教育实验中等级数据分析方法研究

The Study of Analysis Method of Ranked Data in Educational Comparative Experiment

在教育对比实验中,由于受测量工具的限制,学习结果的测评数据往往难以视为等距,所以对获得的等级数据,相应的统计方法也应随之改变.研究了教育对比实验中等级数据的统计检验方法,内容包括等级数据离散程度的熵估计、二维列联表两属性间独立性的χ2检验、相合系数的估值和相合系数的显著性检验.

In educational comparative experiment,due to the restrictions of measure instrument,the testing data of learning results cannot always be regarded as equidistant.As to the ranked data obtained,the corresponding methods of statistics have changed therewith.The essay studies the corresponding and testing methods of sequencing data in educational comparative experiment,including the entropy evaluation of discrete degree in ranked data;the χ2 test of independence between the two in two dimension contingency tables;the appraisement and significance approach of synodical coefficient.
