Abstract: Provided is a method for verifying the accuracy of a response to a web-based survey. The method includes providing a survey on a website and receiving a survey response from an electronic device associated with a respondent, as well as receiving verification data from the electronic device. The verification data is analyzed to determine a likelihood of cheating. The survey response is saved in an authentic database when the likelihood of cheating is below a threshold.

Abstract: A method for managing a survey with a plurality of segments is disclosed. First, one or more segments of the survey is presented to a plurality of respondents. An estimated completion rate is derived for at least one of the segments of the survey and may be based upon a number of respondents presented with the respective segment of the survey, and a number of respondents completing the survey. Quota group progress counts of at least one of the segments of the survey for each of the quota groups is derived. Estimated completion counts of each of the quota groups for at least one of the segments of the survey is also derived. The counts are based upon the corresponding quota group progress counts and the estimated completion rates. The method includes closing the survey to subsequent additional respondents of a given quota group.
