When and why use comparative scales?
- When you need to detect small differences between known stimulus objects (e.g., Pepsi and Coke).
- When you want a scale that is easily understood and applied.
- When you have fewer theoretical assumptions (e.g. about what all constitutes service quality, brand image, etc.).
- When you want to reduce halo or carryover effects from one judgment to another
- When respondent should make a trade-ˇoff (e.g. importance judgments)
- When you have no need to generalize beyond the stimulus objects scaled.
- When the ordinal nature of the data is sufficient for your planned data analysis.
