## 统计代写|描述统计学代写Descriptive statistics代考|Socio-Economic Phenomena

The intent of this chapter is to clarify the nature of socio-economic statistical data, and the role statistics is playing in capturing socio-economic phenomena. This role has been seldom discussed but is a fundamental issue concerning the nature of socioeconomic statistical data, ${ }^{1}$ and the manner in which they convey socio-economic reality. The following discourse may strike some readers as unnecessary, perhaps as not even belonging to statistics. Yet, a good understanding of this preliminary phase should provide the user of statistical data with an understanding of the data-creation process as an important first step of interpretation.

To properly interpret data, an understanding of the nature of the elementary building blocks, $^{2}$ the ‘statistical-counting-units’ and their role in portraying economic phenomena, is needed. A comparison suggests itself with the role that atoms and molecules are believed to play in the physical world. The ‘statistical-counting-units’ could be thought of as equivalents of the atoms in physics. The summation of these statistical-counting-units in statistical aggregates could be compared to molecules that are made up of such atoms. These molecules then make up the substance of objects, which then are somehow comparable to phenomena in the social sciences. Despite the appearance of simplicity and mathematical precision of statistical data presenting socio-economic phenomena, like ‘price level,’ ‘unemployment,’ or the GDP, these phenomena and the data portraying them, are more ambivalent and elusive than is commonly realized.

## 统计代写|描述统计学代写Descriptive statistics代考|The Socio-Economic Phenomena

Let me start with the beginning of any statistical investigation: defining the phenomenon to be studied, what it is, where and when it can be found, and how

it should be captured statistically. To repeat the obvious, the phenomena in society are quite different from phenomena in the natural sciences. They also differ in the manner in which ‘real-life-objects’ project the socio-economic phenomena. ${ }^{3}$ The temperature at which water reaches the boiling point, for example, should be expected to be the same in socialist China as in capitalist USA, in a stone age community in Australia’s outback as in a futuristic community in California. Aside from the influence of the barometric pressure – depending on the altitude above sea level – the boiling point of water was probably the same during the time of the French Revolution as during the Punic Wars of ancient Rome. Minor changes may have occurred in reaction to changes in our solar system and in the galaxy to which it belongs. It seems unlikely that a research grant would be available for studying differences in the boiling points of water between cultures, in different continents, or in different historical epochs. Compare this with research in the social sciences where the opposite assumption applies: nothing should be expected to remain the same from one social stratum to another, from one country or culture to another, or even from one month to the next. Social phenomena are known for their rapid change, their unpredictable evolution and their great variety. Statistical data must keep up with this dynamism, and statistical theory ought to be prepared to interpret the phenomena that underlie those data. It should not be a surprise that statisticians have been uncomfortable approaching this topic. They seem to consider a discussion of economic and social phenomena as lying outside the purview of statistics. $.^{4}$ Yet, a foothold in this foreign area must be obtained.

It appears that socio-economic phenomena can be abstracted from actual situations of society on at least three levels.

## 统计代写|描述统计学代写Descriptive statistics代考|The ‘Projecting Agents’ of Socio-Economic Phenomena

In sociology, economics, management, and other business areas, specific socioeconomic phenomena are portrayed or projected by specific items, events, buildings and all kinds of things such as e.g. cars and in general, ‘durable consumer-goods.’ These ‘projecting agents’ can also be contractual documents that seem to exist only as a piece of paper but are anchored in the laws and customs of society. All of these will be referred to in the following as ‘real-life-objects.’

Socio-economic phenomena, at all levels of abstraction, are projected by appropriate ‘real-life-objects’ as the ‘projecting agents’, somewhat like the invisible field of a magnet is projected by iron filings scattered on a sheet of paper placed on top of that magnet. The iron particles become projecting agents of the phenomenon ‘magnetism’ by their reaction to these polarizing forces that exert an effect on these particles. Quetelet’s example of a circle drawn with chalk on a blackboard comes to mind although he intended to illustrate with it the ‘Law of Large Numbers.’ When looking through a magnifying glass, he relates, the individual chalk particles can be seen, spread randomly over the rough surface of the blackboard. When looking at all those particles together, however, the shape of their array in a circle, which in this instance is the phenomenon, becomes evident. ${ }^{8}$

After the appropriate branches of the social sciences have defined a social or economic phenomenon to be investigated, it is the task of statistics to identify, locate and record those ‘real-life-objects’ that portray that phenomenon.
