How to Write an Effective Survey Questionnaire (Part 1)

Writing an effective questionnaire is not a task for novices. At the very least, it requires an understanding of four basic issues:
1. Considering the differences between a questionnaire that respondents fill out themselves and one that a professional interviewer administers
2. Knowing what questions should be asked early on in the questionnaire, in the middle, and toward the end
3. Understanding how to phrase questions
4. Being sensitive to questionnaire length
