Picking a Random Contest or Survey Winner in SurveyGizmo

I saw a great thread in our survey forum this morning and thought I’d share a couple ideas brought out by our users “Leibiniz” and “donna d.” Donna wanted an anonymous survey to collect data but with a free offer contest to increase the submission rate.

Obviously you need to keep the survey results anonymous, but still collect the personal info to be able to send the winner of the contest their prize. She used a tried and true method of redirecting users who want to enter the contest to separate non-anonymous survey after they complete the first anonymous survey. You can send everyone via a redirect or you could use a question to ask if they’d like to continue on to the second survey. With a little logic thrown in on the respondents who wish to be redirected will. But then she had a problem… how to randomly pick the winner.

That’s when user Leibiniz suggested using http://www.random.org/integers/ to get a random number. What a nice simple little site. You get to set the number of random numbers you want (1 or more winners) and the range of possible values (number of entrants).

Leibiniz and Donna were discussing using a query string variable, but I think a simpler way is to just export your survey data when your survey is complete. Take the number of rows in your survey spreadsheet (minus 1 for the header row) and use this as the maximum value at the Random.org site. Voila! a random user selected by row number.

If you have more questions about surveys, survey contests, or random winners feel free to post here or the forums! Happy surveying.
