Question

Match the LIST-I with LIST-II 

Choose the correct answer from the options given below: 
 

• A. A-I, B-II, C-III, D-IV
• B. A-I, B-III, C-II, D-IV
• C. A-I, B-II, C-IV, D-III
• D. A-III, B-IV, C-I, D-II

Hint:

Use the mnemonic {NOIR} to remember the order and properties of the scales: {N}ominal (categories), {O}rdinal (order), {I}nterval (equal intervals, no true zero), {R}atio (equal intervals, true zero).

Answer 1

The Correct Option is D

Step 1: Understand the Concept: The task is to match the four measurement scales (Nominal, Ordinal, Interval, Ratio) with their defining characteristics. Step 2: Detailed Explanation:
A. Nominal scale: Assigns numbers for identification/classification only. Characteristic: III. Allows for categorizing.
B. Ordinal scale: Allows data ordering/ranking, but interval differences are not necessarily equal. Characteristic: IV. Allows for ranking.
C. Interval scale: Has nominal and ordinal properties, plus equal intervals. Has an arbitrary zero point. Characteristic: I. Arbitrary zero (e.g., 0 degrees Celsius).
D. Ratio scale: Has interval properties and a true, non-arbitrary zero point (absolute zero). Allows true ratio comparisons (e.g., 10 kg is twice 5 kg). Characteristic: II. Absolute zero.
Correct pairings: A-III, B-IV, C-I, D-II. Step 3: Final Answer: The correct match combination is A-III, B-IV, C-I, and D-II, corresponding to option (D).
