Rule of thumb…number of participants per survey item

It’s ten.  For each question on your survey, you should have at least 10 respondents.  And if you’re distributing the survey to more than one group (e.g., participants in a CME activity and representative non-participants), there should be at least 10 respondents per survey question per group.
