摘要
目的检验数据的变异系数是否齐性。方法采用参数及非参数方法检验变异系数。结果应用u体验和χ2检验实现变异系数的检验。结论变异系数检验方法可用于单样本、两样本及多样本资料,在医学科研中具有应用意义。
Objective: The homogeneity of coefficients of variation can be tested.Methods:The parametric and nonparametric statistical procedures can be applied to testing differences of coefficients of variation.Results: Test of coefficients of variation can be conducted by u test and χ2 test.Conclusion: Testing of coefficients of variation may be in appling to one-sample,two-sample,and multisample data,and it may be significance in medical research.
