Survey question writing is a difficult science and a magical art. There are so many intricacies that researchers must learn. Include a “none of the above” where appropriate. Be sure to include a zero. Be sure to include an upper limit. Be sure you don’t miss an option. Be sure not to overlap options. But here’s a rule you may not have encountered before, a rule that is often ignored.
I invite you to answer only ONE of the following two questions, the correctly designed question. Those of you who know the rule will find this an easy task. For everyone else, I hope once you figure out what the rule is that you will keep it top of mind the next time you’re tasked with writing a survey.
