When collecting data, it always collects data from several aspects and angles according to a certain purpose. In data sorting and statistical analysis, data are classified according to these aspects and angles. We call classified data as classified data. Categorized data breaks the individual form of survey data, and no specific survey object can be seen from the data. It is an objective reflection of a certain aspect of all survey objects and is the focus of theoretical analysis and statistical analysis. Theoretical analysis of classified data serves to demonstrate specific research hypotheses. In conducting investigations and research, certain research hypotheses or specific goals must always be put forward. The purpose of theoretical analysis of survey data is to prove whether the research hypotheses are valid. Research hypotheses are divided into central research hypotheses and specific research hypotheses; the former is always proved by overall data to solve the integrity of investigation and research, and the latter is related to the central research hypothesis, which solves the specific aspects and partial problems of investigation and research, and uses classification Proof of information. The rational analysis of classified data and specific research hypotheses can be roughly divided into three levels: the first level is to state classified data; the second level is to conduct generalization and conclusive analysis; the third level is to demonstrate specific research hypotheses.

The collection of information is always based on a number of aspects and perspectives for a certain purpose. In the collation of information and statistical analysis, information is classified according to these aspects and angles, and we refer to classified information as classified information. The classification data breaks the individual form of the survey data, and it can't see the specific investigation object from the data, it is an objective reflection of the situation of all the survey subjects, and it is the focus of theoretical analysis and statistical analysis. The theoretical analysis of classified data is to prove the specific research hypothesis. To investigate and study, we must always put forward certain research hypothesis or specific purpose, and the purpose of the theoretical analysis of investigation data is to prove whether the research hypothesis is true. The research hypothesis is divided into the central research hypothesis and the specific research hypothesis, which solves the wholeness of the investigation and research is always proved by the overall data, and the latter is related to the central research hypothesis, which solves the specific aspects and parts of the research and is proved by the classification data. The rational analysis of classification data and specific research hypothesis is generally divided into three levels: the first level is the statement classification data;

When collecting information, we always collect information from several aspects and angles according to a certain purpose. In sorting out data and statistical analysis, data are classified according to these aspects and angles. We call classified data classified data. Classified data breaks the individual form of survey data, from which no specific survey objects can be seen. It is an objective reflection of a certain aspect of the situation of all survey objects, and is the focus of theoretical analysis and statistical analysis. The theoretical analysis of classified data serves to prove the hypothesis of specific research. The purpose of theoretical analysis of survey data is to prove whether the research hypothesis is tenable. Research hypothesis is divided into central research hypothesis and specific research hypothesis; the former is always proved by general data to solve the integrity of investigation and research, while the latter is related to central research hypothesis, which is proved by classified data to solve the specific aspects and parts of investigation and research. The rational analysis of classified data and specific research hypotheses can be roughly divided into three levels: the first level is to state classified data; the second level is to make summary and conclusive analysis; the third level is to demonstrate specific research hypotheses.<BR>
