在《社会经济统计学原理》的“统计分组”一节中,我们经常看到:“上组限不在内”原则,即属于上组限的单位数不应包括在本组。对此,我们不防多想想社会经济现象,从而不难发现此话未必妥当。 在统计工作中,为了保证变量的分组不致发生混乱,习惯上是根据不同现象特点来归组整理。对于低限规定(控制下限),即一般说越高越好的现 In the “Statistical Grouping” section of the “Principles of Socio-Economic Statistics”, we often see the principle that “the upper limit is not included”. That is, the number of units falling within the upper limit should not be included in the group. In this regard, we do not think about the socio-economic phenomena more, so it is not hard to find that the remark is not necessarily proper. In the statistical work, in order to ensure that the variable grouping will not be confused, it is customarily grouped according to different phenomena and characteristics. For the lower limit (lower limit of control), generally speaking, the higher the better
