How to implement a speeder check - quality control

Question

Dear SoSci team,

I have started a survey and after the soft launch I have realised that some participants are simply too fast, indicating poor quality data.

To control for this, I would like to implement a speeder check, meaning that if someone is below a set time limit by the end of the questionnaire, they would be redirected as a speeder (via a quality redirect link).

Specifically, I would like to set the speed limit to be at 8 minutes max.

Could you help me with how to implement that?

Thank you!
Best wishes

Answer 1

The PHP code on the redirect page would be something like...

if (caseTime('hitherto') < 8 * 60) {
    redirect('https://My.Speeder.Redirect');  // Enter the correct link here
}
