Match Column I with Column II by using the codes given below : Codes : (P) (Q) (R) (S)Column I (Attitude Scale) Column II (Author) (P) Equal Appearing Interval Scale (1) Osgood et. al (Q) Social Distance Scale (2) Thurstone (R) Scalogram Analysis (3) Bogardus (S) Semantic Differential Scale (4) Guttman
(2) (3) (4) (1)
Each attitude scale is linked to the psychologist who developed it:
| Attitude scale | Author | Why |
|---|---|---|
| (P) Equal Appearing Interval Scale | (2) Thurstone | L. L. Thurstone and Chave (1929) had judges sort statements into 11 piles; each item's median value places it at equal-appearing intervals. |
| (Q) Social Distance Scale | (3) Bogardus | E. S. Bogardus (1925) measured acceptance of ethnic groups, from admitting to marriage down to excluding from the country. |
| (R) Scalogram Analysis | (4) Guttman | Louis Guttman's cumulative scaling: items are ordered so that agreeing with a stronger item implies agreeing with all weaker ones (coefficient of reproducibility). |
| (S) Semantic Differential Scale | (1) Osgood et al. | Osgood, Suci and Tannenbaum (1957) used bipolar adjective pairs, yielding evaluation, potency and activity factors. |
The matching therefore reads (P)–(2), (Q)–(3), (R)–(4), (S)–(1).
Hence, the answer is (2) (3) (4) (1).
