Validation
The validation node is used to conduct necessary verification of respondents. Through verification, it ensures that respondents meet specific sample requirements, improving the representativeness and relevance of the sample. The verification mechanism can also be combined with incentive systems to ensure rewards are distributed to genuine respondents, preventing abuse. In scenarios where questionnaire data collection must comply with specific privacy and data protection regulations, the verification mechanism helps ensure compliance.
