Statistics of the general idea is always to stand in the statistical study of the overall perspective of the formation of a large number of observation and understanding of the law law of large numbers and a series of so-called 'stand above', 'grasp the overall situation' is manifestation of this idea, which requires statisticians at work, so that the original aim, because the overall data from the individual body as a bearer of an integrated collection came after, and the individual data vary widely, some boundaries have difficult to judge. Then you need to stand in the overall point of view, to see which meet the general requirements, which do not meet the general requirements, to avoid the 'bystander, Like father,' to avoid deviation from the statistical function itself.

Mean to be the object of study is a concise and important representatives, involving almost all the statistical mean of the concept of the theory is the basic idea of ??statistics and it tells us that the development of statistical understanding of the problem is from the general regulation, the focus is not on the total size of or individuals, reflecting the view of the number concept and inference. mean the whole idea is also required, but requested to observe the general trend to avoid the interference of the individual by chance, it also reflects the overall concept.

Statistical studies of similar general characteristics of the phenomenon, its premise is that the overall characteristics of each unit there are differences. If there is no difference between the various units, there is no need for statistics, if the differences between the various units is based on known conditions can be assumed in advance, there is no statistical method statistical method is to understand the difference in the number of things . statistics reflect the variation of the more basic concept is the variance, is that 'variation' of the 'average' concept can be said that these two concepts mean and variance, respectively, play a 'significant differences with an implicit' and 'knowledge with the police different 'role. the average and variance are the characteristics of similar things in the abstract and macro-metrics.

Estimated to speculate that the overall sample, is the same type of things, getting from here to understand method using estimation methods have a default: the same sample with the overall nature of the sample can be representative of the population, but the representativeness of the sample by incidental factors , the theory of confidence in estimating the degree of measurement is a necessary step to maintain rigorous logic.

Marxist philosophy that things are generally linked, in a changing, often go hand in hand some things were changed or the attendant circumstances were present, the overall number of individual firms is again composed of these individual things are interrelated, we the study of things in general is based on the homogeneous formation between individuals in general, the overall total and the other are mutually related. related to the concept of performance is the relationship between things.

Statistical methods are always inductive, its conclusions will always carry with them certain probability, based on local characteristics and laws of the promotion can not be completely out to determine the credibility, the inspection process is the use of samples to test in advance of the actual data some general quantitative characteristics of the credibility hypothesis.

The five aspects of statistical work, the design is the foundation, said that statistics is a scientific methodology, the most important is reflected in the statistical design, statistical work can achieve the goal, the key is whether the design and if the statistics as a product production process, statistical design is equivalent to product design, the survey is the construction, statistical collation is the assembly, quality inspection and statistical analysis is to analyze and publish statistical information on the application is advertised and sold. Each link has a strong technical, but the design and analysis are technical, most theoretical work, the special statistical functions mainly in two aspects. Statistical design is actually telling the operator how to investigate, how to organize, analyze, and information dissemination is to tell the user what can be achieved statistical purposes, which aims to reach the professional level. why statistics developed so seriously, why the United Nations Statistical Commission set up a special key is also reflected in the two aspects.

Today's society, statistics have been well developed, whether it is data collection method, or statistical study of the law, the objective is to understand the object of our study, or general understanding of statistics. Statisticians sorted out from the beginning of the investigation to the Foreign Service system data, this process makes the overall appearance of statistical people have a better understanding, if the back can we find the internal features from digital, we can conclude that the phenomenon of development of the law, combined with social and economic operation of law, the can raise the effective management of social and economic recommendations. statistical indicator system is a complete scientific system, approved by a number of statistical indicators is a scientific meaning, there is a strict division of labor between the indicators. Therefore, another analysis of the statistical analysis is can not be compared.

In a market economy period, a comprehensive system of statistics they need to have some basic statistical operations, expertise and relatively fixed statisticians to complete the relative stability of the statistics team, you can gain experience for enterprise management and make greater and faster contribution if the sense of duty, self-motivated enough, low quality services, is bound to be adversely affected work. statisticians should be good at learning, and constantly improve their professional quality, be able to do their jobs the same time, business units, business systems, particularly in business Group needs to have a sense of responsibility, sense of the times, and a pioneering spirit of innovation and high professional quality, able to lead and work colleagues in a study of statistical charge.

With the development of society, the status of statistics in our country more and more, more and more attention, more and more perfect system of statistical thinking, I believe the near future, China's statistical work will not join the higher level level.
