在统计指数部分的教学与研讨中,涉及最多的是综合指数、平均指数及平均指标指数。区分它们的关键是要熟练掌握对简单现象总体与复杂现象总体的理解。简单现象总体是指构成现象总体的单位可以直接加以总计的总体。如学生人数、单一商品的销售量、同一种产品的产量等。复杂现象总体系指构成现象总体的单位不能加以总计的。如不同计量单位和价格的商品销售量、不同使用价值和价格的异类商品等。统计指数主要研究复杂现象总体,但也研究简单现象总体。如何区分并熟练掌握这两类总体与以上三种指数,是教学与研讨中十分关键的问题。本文试就此
In the part of teaching and research in the statistical index, the most involved are the composite index, the average index and the average index. The key to differentiating them is to master the general understanding of the general and complex phenomena of simple phenomena. Simple phenomenon refers to the overall phenomenon of the overall unit can be directly totaled. Such as the number of students, sales of a single product, production of the same product and so on. Complex phenomenon refers to the overall phenomenon of the units can not be aggregated. Such as different measurement units and prices of goods sold, different value and price of different goods and so on. The main research index of complex phenomena overall, but also to study the overall phenomenon of simple. How to distinguish and master these two kinds of generalities and above three indexes is a very crucial issue in teaching and discussion. This article try this
