Show answer & explanation
Correct answer: C
Concept
A measurement scale is ordinal when its categories have a meaningful order, but the distances between adjacent categories are not assumed equal. Nominal variables name categories without an inherent order, while interval variables have equal units but no true zero.
Application
Rank of army personnel follows a hierarchy. The categories can be ordered, but the gap between consecutive ranks is not a fixed numerical distance; therefore it is ordinal.
Religion and caste are category labels with no inherent quantitative order; therefore they are nominal variables.
Annoyance levels such as low, moderate, and high have a meaningful order, but the gaps between the levels are not necessarily equal; therefore this variable is ordinal.
Celsius temperature has meaningful equal differences, but 0 °C is not a true absence of temperature; therefore it is an interval variable.
Cross-check and contrast
Scale | Examples in this item | Defining feature |
|---|---|---|
Nominal | Religion; caste | Categories without an inherent order |
Ordinal | Army rank; annoyance level | Ordered categories without assumed equal gaps |
Interval | Celsius temperature | Equal intervals without a true zero |
Therefore, the ordinal variables are A and D, and the accepted value is “A and D only”.
