Question

Match List I with List II:

LIST I(Scale of Measurement)		LIST II(Examples)
A	Nominal	I	Division of people on the basis of their Socio Economic Status
B	Ordinal	II	Diagnostic groups of Mental Disorders
C	Interval	III	Measurement of weight
D	Ratio	IV	Measurement of temperature on a centigrade scale

Choose the correct answer from the options given below:

• A. (A)→(I), (B)→(II), (C)→(III), (D)→(IV)
• B. (A)→(II), (B)→(I), (C)→(IV), (D)→(III)
• C. (A)→(I), (B)→(III), (C)→(IV), (D)→(II)
• D. (A)→(III), (B)→(IV), (C)→(I), (D)→(II)

Hint:

Nominal: naming or categorizing, Ordinal: ranking, Interval: numerical scale without true zero, Ratio: numerical scale with absolute zero.

Answer 1

The Correct Option is B

The different scales of measurement are used based on the nature of the data:

• Nominal Scale (A): Used for categories without numerical ranking, such as diagnostic groups of mental disorders (II).
• Ordinal Scale (B): Represents rank ordering, such as socio-economic status levels (I).
• Interval Scale (C): Contains equal intervals between points but lacks a true zero, such as temperature on a centigrade scale (IV).
• Ratio Scale (D): Includes a true zero, allowing for meaningful comparisons like weight measurement (III).
