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: Understanding the Concept:
The question requires matching the four levels of measurement scales (Nominal, Ordinal, Interval, Ratio) with their defining characteristics.
Step 2: Detailed Explanation:

A. Nominal scale: This is the most basic level of measurement. It involves assigning numbers to objects or events simply for identification or classification. Its only function is to III. Allows for categorizing.
B. Ordinal scale: This scale allows data to be ordered or ranked, but the differences between the ranks are not necessarily equal. Its key feature is that it IV. Allows for ranking.
C. Interval scale: This scale has the properties of nominal and ordinal scales, plus the characteristic that the intervals between the units are equal. However, it lacks a true zero point; its zero is arbitrary. A key characteristic is its I. Arbitrary zero (e.g., 0 degrees Celsius).
D. Ratio scale: This is the highest level of measurement. It has all the properties of an interval scale but includes a meaningful, non-arbitrary zero point, known as an II. Absolute zero. This allows for true ratio comparisons (e.g., 10 kg is twice as heavy as 5 kg).
The correct pairings are A-III, B-IV, C-I, and D-II.
Step 3: Final Answer:
The correct combination of matches is A-III, B-IV, C-I, D-II, which corresponds to option (D).
