Matching Attitude Scaling Techniques with Computational Features
This solution identifies the correct computational feature for each attitude scaling technique listed.
Key Concepts
- Paired Comparison: Items are compared in pairs. Scale values are often derived using standard scores like Z-scores.
- Scalogram (Guttman Scale): Assesses unidimensionality using the Coefficient of Reproducibility.
- Equal Appearing Intervals (Thurstone Scale): Scale values are determined by the median of interval judgments.
- Summated Ratings (Likert Scale): Item selection relies on item analysis, such as item-remainder correlation.
Correct Pairings
The accurate matches between the techniques (List-I) and their computational features (List-II) are:
- a. Paired comparison corresponds to ii. Computes Z-scores as estimates of scale values.
- b. Scalogram corresponds to iii. Computes coefficient of reproducibility.
- c. Equal appearing intervals corresponds to i. Computes median category as scale values.
- d. Summated ratings corresponds to iv. Computes routine measures of item analysis like item-remainder correlation to select items.
