What is a scale on which a pairs of opposite adjectives are presented called ?

[a] Visual analogue scale
[b] Guttman scale
[c] Semantic differential scale
[d] likert scale

✅ Correct Answer:
[c] Semantic differential scale

🔍 Explanation:
✅ [c] Semantic Differential Scale

Developed by Charles Osgood, this scale is used to measure people's attitudes or feelings toward a concept.

Pairs of opposite adjectives (e.g., happy–sad, strong–weak, clean–dirty) are presented.

Respondents rate a concept (person, idea, product) on a 7-point or 5-point scale between the adjective pairs.

Respondents mark the point that best reflects their perception.

❌ Other Options:
[a] Visual Analogue Scale

A straight line where respondents mark their position on a continuum (e.g., from no pain to worst pain).

No adjective pairs, just extremes.

[b] Guttman Scale

A cumulative scale used to measure agreement with increasing intensity.

Responses build on each other in a logical order.

[d] Likert Scale

Measures level of agreement or disagreement with a statement (e.g., Strongly Agree to Strongly Disagree).

Does not use adjective pairs.
