some of the people took my survey only partially.
Can I find out, what was the problem? When I look at the results I found out they submitted the survey 2 times.
Maybe there is a question that requires a certain input/information that they are not understanding or not willing to give?
I would like to learn what is the reason for that behavior and improve the survey.
You may consider running a Fall-Off report to see where respondents are dropping off your survey:
Note: this does require a Pro or Enterprise Account.
Additionally, you may want to export your survey data to excel. This will give you a raw data file that contains all response data and might help you see patterns with regard to the Partial respondents:
I hope this gives you some options!
