The correct answer is
(i), (iii) and (v)
Classifying Variables: Nominal Category Focus
This question requires identifying which variables from the list are exclusively classified as nominal. A nominal variable represents categories that have no intrinsic order or ranking.
Understanding Variable Types
Let's analyze each variable:
- (i) Eye colour: Categories like 'blue', 'brown', 'green'. These are distinct labels with no inherent order. Thus, it is purely nominal.
- (ii) Military rank: Categories like 'Private', 'Sergeant', 'Captain', 'General'. These ranks have a clear hierarchical order. Thus, it is an ordinal variable, not purely nominal.
- (iii) Type of cheese: Categories like 'Cheddar', 'Mozzarella', 'Brie'. These are distinct types with no inherent order. Thus, it is purely nominal.
- (iv) Scores in a test: Scores like 75, 80, 92, or grades like A, B, C. These represent quantities or ordered levels, making them interval/ratio or ordinal, not purely nominal.
- (v) Political party affiliations: Categories like 'Democrat', 'Republican', 'Independent'. These are distinct labels without an inherent order. Thus, it is purely nominal.
Identifying Purely Nominal Variables
Based on the analysis, the variables that can be classified *only* under the nominal category are:
- (i) Eye colour
- (iii) Type of cheese
- (v) Political party affiliations
Therefore, the correct option includes (i), (iii), and (v).
