Correct Answer Explanation
At the second stage, 4 sub-classes are created: Married Male, Unmarried Male, Married Female, Unmarried Female.
Two-Stage Qualitative Classification:
- Stage 1: Population → Male / Female (2 classes)
- Stage 2: Male → Married Male / Unmarried Male; Female → Married Female / Unmarried Female (4 sub-classes)
Key Points:
- Stage 1 is based on presence/absence of 'male' attribute.
- Stage 2 is based on presence/absence of 'married' attribute within each gender class.
- This is a classic example of hierarchical qualitative classification.
