What is the difference between comparative scales and non-comparative scales?

Answer 1

Comparative scales involve the respondent in signaling where there is a difference between two or more producers, services, brands or other stimuli. Examples of such scales include; paired comparison, dollar metric, unity-sum-gain and line marking scales. Non-comparative scales, described in the textbook, are; continuous rating scales, itemised rating scales, semantic differential scales and Likert scales.The best way to find a comparative scale is to look for relative choices. Rank orders also are comparative scales.Non Comparative scales are more like your rank from 1 to 5 or 1 to 10 surveys.Hope that helps!
