Explanation of census terms, explanation of typical survey terms

Census refers to a one-time large-scale comprehensive survey specially organized by a country or a region for the purpose of investigating in detail an important national condition and national strength, and it is mainly used to investigate the data that cannot or are not suitable to be collected by regular and comprehensive survey reports, so as to find out the important national conditions and national strength.

Expansion: Census refers to a one-time large-scale comprehensive survey specially organized by a country or a region for the detailed investigation of an important national condition and national strength, which is mainly used to investigate the data that cannot or is not suitable to be collected with regular and comprehensive survey reports, so as to find out the important national conditions and national strength.

It is one of the organizational forms of statistical surveys. The work of conducting a survey of all units of the statistical population to collect statistical information. Census data are often used to provide a complete picture of a phenomenon at a given point in time.

For example, the census is to survey and register the population of the whole country one by one, and stipulate a specific time point (a certain year, a certain month, a certain day, and a certain time) as a unified national statistical time point, so as to reflect the various natural and social characteristics of the population concerned.

It is defined as a one-time comprehensive survey organized specifically for a specific purpose.

The explanation of typical survey terms is a kind of non-comprehensive investigation based on a comprehensive analysis of the overall research object according to the purpose of the survey, and consciously selects several overall units from it for systematic and thorough investigation.

Its characteristics are: there are few investigation units, and they are consciously selected by the investigators; The content of the investigation is specific and detailed; The investigation takes a short time and the situation is reflected quickly. The main effects of a typical survey are:

Able to conduct specific and in-depth investigations of the research issues and be able to combine investigation with research.

Able to investigate and study new situations and new problems; Combining a typical survey with a comprehensive survey can make up for some of the shortcomings of the comprehensive survey and verify the authenticity of the comprehensive survey figures.

An introduction to a typical survey

Typical investigation refers to the systematic and thorough investigation and study of selecting one or several representative subjects from among several similar survey subjects according to the purpose of investigation and research, so as to understand the essential characteristics and development laws of such objects, and to find out the experiences and lessons worthy of reference that are of universal significance and value. This method is also called "dissecting a sparrow".

Its advantages are that the things understood are vivid and concrete, the information is detailed, the research on the problem is in-depth and detailed, and the investigation methods are flexible and diverse. You can stay in the field for a long time to go deep into the actual situation, directly observe, or hold investigation meetings or individual visits. There is also not much manpower invested.

However, the scope of the investigation is narrow, and it is difficult to reflect the whole picture.

Statistical survey is a statistical work process that uses scientific survey methods to collect data and information in a planned and organized manner according to the purpose and requirements of the survey.

Statistical survey is a statistical work process that uses scientific survey methods to collect data and information in a planned and organized manner according to the purpose and requirements of the survey. According to the different institutions that organize statistical surveys, statistical survey items are divided into three categories: national statistical survey projects, departmental statistical survey projects, and local statistical survey projects.

Statistical Survey: The work of collecting various statistical information in an organized manner.

Descriptive Statistics Terminology Explanation: A part of statistics. A general term for the various methods used in the initial stage of statistical analysis. This paper mainly studies how to carry out various simplified data methods that can not only describe the whole picture of the group of data, but also reflect the content and essence of the phenomenon to be studied.

The content includes statistical grouping, compilation of statistical tables, drawing statistical charts, and calculating various statistics, such as arithmetic mean, median, mode, geometric mean, harmonic mean, and other statistics that represent trends or representative values in the data set; Standard deviation, mean deviation, four-point difference, relative difference scale, etc., some statistics that indicate the trend or dispersion of the data.

The number of various correlation quantities that indicate the degree of correlation between two or more columns of variables; Regression coefficients that represent the quantitative relationship between variables, as well as some eigenvalues that represent the state of the distribution, etc.

In order to have a clear understanding of the overall situation of data, the database should study and carry out useful statistical work, that is, data statistics, so as to promote the extensive accumulation and collection of data.

Its work is as follows: quantitative statistics; Custody statistics; Appraisal statistics; utilization statistics; **Situational statistics; Statistics on data reproduction. In order to summarize the work of the whole year and report the work to the management organs, some databases need to compile an annual comprehensive statistical table of information, and its main statistical items are:

The name of the database, the number of data, and the number of data.

Descriptive statistics is the collation and analysis of data through charts or mathematical methods, and the distribution status, numerical characteristics and random variables of the data.

Methods of estimating and describing the relationships between them. Descriptive statistics can be divided into three parts: centralized trend analysis, neutral trend analysis and correlation analysis.

Centralized trend analysis.

Centralized trend analysis is mainly based on averages.

Median, mode.

and other statistical indicators to represent the concentrated trend of data. For example, what is the average score of the participants? Is it a positive or negative bias distribution?

Deviation trend analysis.

The analysis of the deviation trend mainly relies on the full distance and the four-point difference.

Mean Deviation, Variance, Standard Deviation.

and other statistical indicators to study the trend of data deviation. For example, if we want to know which of the two classes has a more dispersed distribution of language scores, we can compare the four points difference or percentage points between the two classes.

Correlation analysis. <>

Correlation analysis** whether there is a statistical correlation between the data. This relationship includes both a single correlation between two data, such as age and personal domain space, and multiple correlations between multiple data, such as age, depression.

The relationship between the incidence and the space of the personal domain.

Macro investigation of modulation model: It is a kind of descriptive research, which is a research method that collects the materials of the research object in a purposeful and planned way through the observation of raw materials, so as to form a scientific understanding. It involves the process of investigating and researching two organic links.

Survey Survey The difference between research and research:

Distinguish. 1. Different interpretations:

Investigation: Investigation in order to understand the situation (mostly refers to going to the scene).

Research: Research and research.

Research: Exploring the truth, nature, and laws of things.

Distinguish. Second, the usage of the Dan book is different:

Investigation: We should go deep into reality, accurately reflect objective facts, not rely on subjective imagination, understand things as they are, and record them in detail.

Research: It is a certain situation, an event, a certain experience or problem, through the investigation and understanding of its objective actual situation in practice, and the investigation of all the information and materials learned from the investigation to "remove the rough and fine, remove the false and retain the true, from this and that, from the surface and the inside" analysis and research, reveal the essence, find out the law, summarize the experience, and finally state it in writing, which is the research.

Research: On the basis of grasping objective facts, carefully analyze and thoroughly reveal the essence of things.

It is to systematically sort out the materials collected in the investigation after an in-depth and detailed investigation of a certain work, an event, and a problem, analyze and study, and report to the organization and leaders in writing.

Corresponding explanation sampling survey method: It refers to a survey method that selects a part of the units from all the units of the research object for investigation and analysis, and uses the quantitative characteristics of these units to infer the quantitative characteristics of the population. Among them, all the units of the subject of the study are called "population"; The group of subjects who are extracted from the population and actually investigated is called a "sample".

In sample surveys, the determination of the sample size is a key issue.

Census is a statistical principle that proposes a systematic approach that can be used to collect data, analyze data, and report results. Censuses rely on planning and structure, and are primarily used to collect, aggregate and report data on population, resources and the environment, as well as information on how these data affect policies and the economy.

Fundamentally, census is a systematic method of data collection that aims to collect data about a particular region or population in order to understand the characteristics of that region or population and,** and how decision-makers make decisions about the region or population. Censuses typically include the collection, analysis, and reporting of dynamic, structured, or multidimensional data.

The purpose of the census is to provide objective information on multiple objectives, and as a result, to support policy formulation and problem-solving. The census data collection process usually starts with defining a region or population, then determining the types of data to be collected, then proceeding to data collection, and finally data analysis and reporting.

Censuses are an effective way to collect data on social, economic, and environmental aspects, as well as how decisions are made about that data. Censuses also collect data on population, resources, and the environment, and how that data affects policies and the economy, helping to make more informed decisions.
