摘要
为丰富体育统计和测量评价的教学和研究内容 ,以文献资料法和数理统法对r×C列联表的有关问题进行了探讨。结果表明 :随着r或C值的减少 ,列联系数随之下降 ,而显著性水平不断上升 ;不同分类标准影响列联系数和显著性水平 ;对称性r×C列联表基本能含括非对称性列联表的一些特征 :r×C列联表与C×r列联表的计算结果和检验结果不同。
With the documentary method and statistics method,some questions about r×C table were discussed to enrich the contents of statistics and measurement and evaluation in physical education The results show that,first,the significant level increases and the correlation coefficient decreases as the value of r or C decreases Second,different classification standards influence the coefficient and the signficant level Third,the characteristics of symmetric r×C table can involve that of the asymmetric r×C table Finally,the r×C table is different from the C×r table in calculation and test results
