兵器试验中两种产品均值比较的统计方法

Statistical Method of Two Products Average Comparison in Weapon Test

针对兵器试验中2种产品均值比较的问题,提出一种利用假设检验进行数据处理的方法。通过均值比较的不同形式建立相应的假设,根据总体方差的不同情况选取适当的统计量,并根据实测样本对所做的假设进行检验,从而判断此假设是否合理,做出最后决策。实例应用表明:该方法合理有效,不仅适用于均值比较的检验,对方差比较等均可进行检验,是兵工产品指标测定的一种有效方法。

For the problem of two products average comparison in weapon test, this paper put forwards a method of processing data by hypothesis test. Corresponding hypothesis is established by the comparison of the average different forms, the appropriate statistics is selected according to the different situation of population variance, the sample is measured according to the reasonableness of the hypothesis test, and our final decision is made. The application example shows that this method is reasonable and effective. It＇s not only applicable to average comparison test, but also to the variance comparison test, which is an effective way to test the indexes of military products.
