How can I require a response to a question?
When you add questions to a survey, by default, validations are turned off. When validations are not enabled, respondents can simply continue with the survey without actually selecting answers. If respondents go through all the pages in the survey without selecting answers, the response is still considered as complete.You can enable validations to make a question required so that respondents can continue with the survey only after responding to the questions.
Is there an easier way to enable validation?
Yes, you can enable validation by checking on the Make Required (*) box on the fly-out menu. You need not go to the Settings page to enable validation.
