The characteristics of indicators and the relationship between indicators and quantitative signs;
1, characteristics of indicators
Indicators explain the characteristics of the whole, and signs explain the characteristics of the whole. Indicators only reflect the quantitative characteristics of the population, and all indicators can be expressed by numerical values. On the other hand, symbols include both quantity symbols and quality symbols that reflect the characteristics of overall unit quantity. Only quantity symbols are represented by numerical values, and quality symbols are represented by attributes.
The index value is obtained through a certain summary, but the quantity mark in the mark can be obtained directly without summary. Signs generally do not have the conditions such as time and place, but as a complete statistical index, we must talk about time, place and scope.
2, the number of indicators and signs.
There is a conversion relationship between indicators and quantitative indicators, that is, due to different research objectives, if the original statistical population and the original statistical indicators become a whole unit, the corresponding statistical indicators will also become quantitative indicators, and at the same time, the indicator name will become a symbol, and the indicator value will become a symbol value or a variable value.
