Questionnaire design is both art and science - but much of the science continues to be ignored by researchers today. Jeffrey will share design practices informed by research on research that you can immediately begin to apply. He'll review the science on agreement scales, yes/no questions, numeric scales, scale ordering, all-that-apply questions, bipolar scales, and more. And he'll share examples of the art of it: times when he has had to set aside the science. If you write questionnaires, you'll want to attend this webinar.
