Open-Ended Questions vs. Close-Ended Questions
Open-ended questions allow the survey participants to elaborate on a
particular issue and offer insights on topics you may not have thought of.
That having been said, it’s probably best to use a combination of the two,
with most of the survey questions being close-ended.
The reason for having the majority of questions close-ended is that you can guide survey participants more to extract the information that is most important to the issues being researched.
