This is an example of a great survey question! You can say that it is a leading question, but the actual question is not controversial and so I'd say it's okay. It is a close-ended question with multiple choices. There is an option for everyone: 0- 5+ finals, and it is very easy to understand. The poll gives you the results right away and it even gives a tally of how many people have been surveyed so you know what the percentages really mean!
Great job UMN.
