Small and medium-sized enterprises to start their businesses, and whose carrying capacity is generally less than tens of thousands. The Special Database stronger anti-fraud capability is reflected in the fact that the survey results will far exceed the control capability of manual review. If data is tainted, it can lead to deviations in product strategy. In the field of research, "reliability" is used to measure the reliability of research, which refers to the degree of consistency in the results Special Database obtained when the same method is used to repeatedly measure the same object. Questionnaire star emphasizes "strictly according to valid samples to price. To put it simply, there are 4 steps in the sample control of Questionnaire Star. First, it is targeted to the respondents according to the needs of customers, and the Special Database samples required for review are screened out by screening questions, and then the pollution data such as the wool party is restricted through mechanisms such as IP restrictions and identification of the same device, and finally the effective samples are Special Database priced. But as long as there is interest, the wool party is indispensable. On Zhihu, there are a lot of cases of data being polluted by the wool party. One of them is that 3,000+ questionnaires and 3,500+ yuan red envelopes. Were maliciously swiped away from the questionnaires posted on Questionnaire Star. At the peak, up to 300 copies were submitted per minute, even if a single device Special Database was set to submit only once didn't work either. It is not difficult to see that once the total amount of questionnaires sent and recovered is too large and the time is too tight, it is difficult to avoid being maliciously swiped away rewards. Obviously, Special Database in the second half when the demand for data accuracy continues to increase and investigations become increasingly intensive, the traditional quality control mechanism is no longer sufficient.
