Hi Pat,
Interesting. You may be able to do this with a custom script. We would have to add the rand() function in for you this wouldn’t be too much of an issue, but yes you can do this inside a survey.

It would be difficult to tell the system how many people to give the incentive to. It would basically run the random function generate a random number, and if that random number equals some constant (basically the percentage of people you want to give this incentive to) then give the incentive.

So while you can assign a percentage the exact number of people getting the incentive (like a quota) would be very difficult, and may be easier to do after the survey is finished.

Hope this helps,
Chad

Hi researcher,

Actually it's called sgapiRand().  Sorry, we just forgot to put it in the documentation.  I'll have our tutorial guy add that in on Monday.
