摘　　要：参数统计方法都是已知总体分布,对其分布的总体参数进行假设检验。在试验法研究调查中,常常采取最传统的方法,分为试验组和对照组两组进行研究。然而,在实际生活中由于研究问题的复杂性,往往需要研究多于两组的研究对象之间的差异,在参数统计中,常常需要数据符合正态分布假定,但是,当先验信息不足以支持正态分布时,就要采取非参数方法解决。说明了非参数估计的方差分析法,阐述了两种检验方法,并将其运用到检验杀虫剂药效当中。Parameter statistical methods are known population distribution, the distribution of population hypothesis test. In the test method research,traditional method which divided into trial group and control group. However, with the complexity of the research problem more than the difference between two groups of object must be stUdied. In parametric statics, date always need to conform to de normal distribution assumption. When a priori information is insufficient to support normal distribution, a nonparametric approach should be taken. Illustrates the nonparametric estimation variance analysis method and expound the two test methods, and applied to the inspection of pesticide efficacy.
