Problems solved by technology
But at the same time, the data quality of the online questionnaire survey has also been questioned. There is a problem that the respondents of the online questionnaire survey ignore the content of the questionnaire and answer silently, perfunctorily or without answering, which leads to a decrease in the credibility of the questionnaire, resulting in low data quality.
For such problems, related background technologies focus more on the identification and control of non-answer questions, and lack convenient and effective evaluation methods for low-credibility problems caused by tacit and perfunctory answers
There are also some data quality assessment methods such as the combination of subjective and objective methods, which are evaluated from multiple dimensions and are oriented towards comprehensive measurement of data quality, which have shortcomings such as heavy workload, time-consuming, not strong pertinence, and not convenient enough

Embodiment Construction
[0030] The present invention uses a questionnaire survey on the travel mode of Xiamen residents as a case to illustrate the implementation method of the credibility evaluation method of the network questionnaire survey. Specifically, it includes the following steps:
[0031] a. Compile a questionnaire on the travel mode of Xiamen residents. The questionnaire includes 10 questions, as shown in Table 1.
[0032] b. Based on the time used to quickly read the text of the questionnaire, set the total time used for the questionnaire survey reference answer and the reference time for each question answer, see Table 2.

A method for evaluating the credibility of a network questionnaire survey, comprising the steps of: a, designing the timing function of the answer page of the network questionnaire survey, including the total time spent on answering questions and the time spent on answering each question; c. Calculate the evaluation index value and judge the credibility of the online questionnaire survey. The present invention is based on designing the answer timing function, analyzes the relationship between the answering time of the respondents in the network questionnaire and the reference answering time, constructs an evaluation index system and evaluation standards, and realizes low reliability due to tacit answering, perfunctory answering or no answering. Identification and evaluation of reliability questionnaires. This method will provide a fast, convenient and effective method to improve the credibility and data quality of the online questionnaire survey.
Description
Technical field [0001] The invention relates to a method for evaluating the credibility of a network questionnaire survey, which belongs to the technical field of social survey and network technology. Background technique [0002] With the development of the Internet, online questionnaire surveys are increasingly emerging and widely used in various industries and fields. Compared with traditional paper questionnaire surveys, online questionnaire surveys have the advantages of convenient survey organization, cost saving, fast recovery, and efficient data management. But at the same time, the data quality of online questionnaire surveys is also being questioned. There are problems that the reliability of the questionnaire is reduced because the respondents ignore the content of the questionnaire, answering silently, perfunctorily, or not answering, resulting in lower data quality. For such problems, the related background technology focuses more on the identification and control o...
