Use Cases
Build a weighted skills assessment with section scores and overall ratings.
Create a multi-section employee engagement survey with Likert and open-text questions.
Design a product feedback questionnaire with conditional branching based on usage tier.
Generate a vendor evaluation rubric with weighted criteria scores.
Tips
Use Likert scales with an odd number of points (5 or 7) for opinion questions — even-point scales force respondents to choose a side and reduce data quality for ambivalent respondents.
Place sensitive questions (salary, demographics) at the end of the questionnaire — upfront sensitive questions increase abandonment rate.
Pilot the questionnaire with 5 people before wide distribution to surface ambiguous question wording.
Fun Facts
The Likert scale was developed by Rensis Likert in his 1932 doctoral dissertation. It became the most widely used psychometric scale in social science research.
Survey abandonment rates average 20% for surveys under 5 minutes; they climb to over 50% for surveys estimated at 15+ minutes, per SurveyMonkey internal data (2021).
Net Promoter Score (NPS), now used by over 65% of Fortune 1000 companies, was introduced by Fred Reichheld in a Harvard Business Review article in 2003.
FAQ
Questionnaire vs. survey — what's the difference?
A questionnaire is the instrument (the questions). A survey is the full process including administration, data collection, and analysis. All surveys use questionnaires, but questionnaires can be used outside formal surveys.
How many questions is too many?
Keep it under 12 questions for unsolicited outreach; up to 30 is acceptable for opt-in audiences with context. Every question beyond what is needed to answer your research question degrades response quality.
