Is there a way I can make survey takers go back and correct incorrect answers at the end of the survey?
Are you looking for corrections prior to completing (submit) the survey? You can resend a survey back to any respondent if needed for updates or corrections.
But if you are looking for a method to flag incorrect answers prior to submit I would suggest to use Validation on the question itself. That would prevent moving forward without the correct answer.
I am not sure what type of questions you are referring to that could be answer incorrect.
So here are a few examples and if I have missed your question, please explain further.
So for example
Essay Question – use the items like character and word count
Text box – use the auto suggest or default answer or verify based on previous question, use HTML placeholder.
