Question

Which of the following is a nominal variable?

• A. Blood sugar level
• B. Temperature
• C. Mother-tongue
• D. Cost of a cup of tea

Hint:

Nominal variables categorize data without any rank or numeric value, such as language, gender, or religion.

Answer 1

The Correct Option is C

A nominal variable is a categorical variable that has no intrinsic ordering or rank.”Mother-tongue” represents a category (e.g., English, Hindi, French) without any quantitative value or natural order. In contrast, variables like blood sugar level, temperature, and cost of a cup of tea are continuous or ordinal in nature.
