What measures has TouchPoll, Inc. taken to ensure that one survey respondent is not taking a TouchPollWEB™ multiple times?
Although with very large samples this scenario is not likely to be problematic, a single respondent who takes a survey several times can have a serious impact on the overall results for smaller groups of survey respondents. To address this potential threat to data integrity, TouchPollWEB™ features the ability for account holders to request a custom web address be sent to each intended survey respondent. This measure preserves respondent anonymity, but does not allow for the person to re-enter the address once they have completed the survey. In other words, they cannot enter the link and take the survey again and again.
