The scale that has a unique zero point with properties of order, distance and tags for identification of objects is .................
Ratio scale
S. S. Stevens (1946) classified measurement into four levels. The nominal scale only names or tags objects; the ordinal scale adds order (rank); the interval scale adds equal distances but has an arbitrary zero, as in temperature in degrees Celsius.
The ratio scale has all these properties - identification, order and equal distance - plus a true, unique zero point, so ratios are meaningful, as in height, weight or time taken.
Hence, the answer is Ratio scale.
If you are collecting data on a person’s height, which type of data is this ?
Which of the following is the most similar ?
Identify correct sequence of Steven’s four levels of measurement scales :
(i) Ordinal
(ii) Interval
(iii) Nominal
(iv) Ratio
Codes :
Match Column I with Column II by using the codes given below :
| 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 |
Codes :
(P) (Q) (R) (S)
