时点指标序时平均数的计算及其误差

反映不同时间上的社会经济现象的时点指标相加是没有意义的，而在计算其序时平均数时，必须把不同时间上的时点指标相加，这个矛盾在社会经济统计学原理教材上普遍存在，但却只字未提，本文主要对反映社会经济现象的时点指标的序时平均数计算的理论基础进行讨论，同时，根据非连续调查所得到的间断时点数列计算的序时平均数存在的误差往往被人们忽视，分析其误差产生的根源，也是本文的主要内容。

Computation and Tolerance of the Average Number of the Timed Indeol

It's meaningless of the plus of timed indeol on different phase of social economic phenomena,however on the time computing the order average number,different phrase of Indeol must be considered. The parodaol exists universally in the teaching materials of social economic stastics principle course,which mentions none in the course. The essay mainly discusses the theory basis of computing the average number reflecting social economic phenomena, meanwhile the existence of uncontinuons timed line of average number derived from uncontinuons investigation is often ignored and analyse the origin of the tolerance.
