It is important to understand the implications of response formats on levels of measurement in survey design and quantitative data analysis.
Some commonly used response formats include:
- Dichotomous: e.g., Yes or No
- Multi-chotomous: e.g., Yes, No, or Maybe
- Multiple response: e.g., Tick all that apply
- Likert scale: Equally-spaced intervals, usually 3 to 9 intervals
- Graphical rating: Can mark any point on a continuous scale
- Semantic differential: Put two words at opposite ends of a scale with interval marks
- Idiographic: Use symbols/pictures instead of words and numbers
- For more info see: Rating scale (Wikipedia)
