Set – I (Variable) Set – II (Scale of measurement) (a) Intelligence scores on a Verbal test (i) Ratio scale (b) Ranks of the students in a musical test (ii) Interval scale (c) Number of children in tribal families (iii) Ordinal scale (d) Length and breadth of classroom (iv) Nominal scale
Codes :
(a) (b) (c) (d)
The question requires matching variables from Set – I with their appropriate scales of measurement from Set – II.
We need to determine the scale of measurement for each variable listed in Set – I:
Based on the matching above, the correct sequence is:
Therefore, the code representing the correct matching is (iv) (iii) (i) (ii).
| LIST-I Measurement scale | LIST-II Definition | ||
| A. | Likert Scale | I. | Measures the meanings people create in response to a particular stimulus |
| B. | Semantic Differential scale | II. | Equal appearing intervals between adjacent points of a measurement scale |
| C. | Thurstone Scale | III. | Identifies the extent of a person's attitude towards a person or phenomenon |
| D. | Guttman Scale | IV. | Items are arranged along a continuum |
| LIST-I Scales of Measurement | LIST-II Characteristics |
| A. Nominal | I. Place items from least to most or lowest to highest |
| B. Ordinal | II. Precisely how far apart the items are |
| C. Ratio | III. Denotes the categories only |
| D. Interval | IV. Enables researcher to determine the proportions easily |
