Statistical survey is an important data collection method, which can help us understand the social, economic and cultural situation. According to different organizational forms, statistical surveys can be divided into two categories: statistical reports and special surveys. Among them, special surveys include general surveys, key surveys, typical surveys and sampling surveys. Below, we will introduce these survey methods one by one.

statistics

A statistical report is a report that summarizes and analyzes economic, social and cultural data in a certain period in accordance with the prescribed format and standards. This is a relatively simple data collection method.

ad hoc survey

Special investigation is an investigation method aiming at a specific problem or object. It includes general survey, key survey, typical survey and sampling survey.

Conduct a comprehensive investigation or study.

Census is a way to conduct a comprehensive investigation of a specific object or phenomenon. Usually initiated by the government or other organizations to understand the basic situation in a certain field.

Major investigation

Focus investigation is a way to select some key units among the survey objects for investigation. Through the feedback from these units, we can quickly understand the overall basic situation.

typical investigation

Typical investigation is a kind of in-depth investigation method specially organized. On the basis of comprehensive analysis, we will purposefully select some representative and typical units for detailed research. In this way, we can not only understand the essential characteristics of things, but also explore the causal relationship and development trend.

Random surprise inspection

Sampling survey is a survey method that selects some units from the whole population to form samples according to the principle of randomness. Through the accurate measurement of sample indicators, we can roughly understand the quantitative characteristics of the population.
