used to one answer

- Easier to code
- Rating scales
- Characteristics
- Ask people to provide
"how much" judgments
- Fully labelled scales
are more reliable
- 5 and 7 point scales
are more common
- Types of scales
- High frequency scale
- Alternatives assume
a high frequency
- Low frequency scale
- Alternatives assume
a low frequency
- Graphic rating scale
- Requires a mark along a
continuous line that is anchored
with descriptions at each end
- Semantic differential scale
- Measures the meaning
people ascribe to concepts
- Put a checkmark on different lines
- Non verbal scale
- Open ended questions
