The purpose of a questionnaire survey is to get to know the subject of the survey by means of closed and open-ended questions on the questionnaire. The researcher uses this tool to make accurate and specific measurements of the process of social activities and applies sociological statistical methods to describe and analyze the quantities and obtain the required survey information.
Questionnaire surveys are generally categorized into market and social surveys.
1, market research:
The purpose of market research is to collect enough, true and effective information for enterprises and institutions and other activities and strategies for the management to provide reference basis.
2, social surveys:
The purpose of the social survey questionnaire is to understand the social phenomena by means of questionnaires, to provide a theoretical basis for social research and valuable references, and to listen to the voices of the various strata of the society, which can also be academic surveys.

Categorization of questionnaire questions:
A questionnaire is to include questions in three categories: variables in the theoretical model, auxiliary variables, and questions related to the demographic characteristics. A questionnaire that includes these three types of questions will more accurately get the information needed for the survey.
1. Variables in the theoretical model:
A questionnaire must first include all the variables in the theoretical model. In behavioral research, these variables are often psychological variables. A psychological variable is measured using three or more measurement items. A mental variable often corresponds to a set, rather than a single, semantic meaning. We call such a mental variable a theoretical construct or construct.
2. Auxiliary variables:
The important auxiliary variables are control variables. Control variables are not the main players in a theoretical model. But because a theoretical model is often only from a point of view, the selected variables sometimes can not have a good adequacy.
Then the inclusion of some control variables can be used to show that the selected theoretical variables are still important even if some other important variables are present, and to show that the theoretical variables have an additional role that is distinct from that of the control variables.
3. Demographic Characteristics:
Demographic characteristics include age, gender, race, education, province, and occupation. These variables do not tend to dominate psychological research. Most of these variables are relatively objective and have little reporting error. The purpose of including these variables in a questionnaire is often to test whether a sample is representative by having a similar composition to the population.
