摘要
仅比较离散系数大小来衡量算术平均数代表性有其局限性,可利用假设检验方法加以完成。为此,提出了衡量算术平均数代表性的t检验、F检验和将vs甲与vs乙视作两个比率的t检验等三种假设检验方法,且例证效果良好。
It has its limitation to measure the representativeness of arithmetic mean only by comparing the size of discrete coefficient,but it can be done by using the hypothesis test method.Therefore,this paper proposes three hypothesis test methods to measure the representativeness of arithmetic mean,that is,t-test,F-test,and considering and as the t-test of the two ratios,vs甲and vs乙the example presented in this paper shows the effectiveness of these methods.
