A problem inherit in surveys with reward programs is that lot of people race through the survey without really looking at the questions just to get to the reward.
I'm not interested in warning those respondents, but I'd like to not include those people in the survey results.
Is there a way to use timers or such so that if someone obviously races through the questions, their results are not considered.
Or, short of that, is there a way to see how long it took someone to complete the entire survey?
I understand that people may walk away to do something while in the middle of the survey, but usually those people racing through the survey to get to the rewards don't do that.
