Question
Explain the different forms of qualitative classification data.
✓
Answer
Qualitative classification can take the following two forms:
- Simple Classification: If the data are classified into only two classes, such a classification is termed as simple or dichotomous classification. Male-female, employed-unemployed, educated-uneducated are the examples of dichotomy.
- Manifold Classification: If in a classification, data involves more than one characteristic, it is called manifold classification. A qualitative classification is referred to as a manifold classification in each of the two cases explained below.
- When the given population is classified into more than two classes with respect to a given attribute such as intelligence, beauty, etc.
- When the given population is first classified into two classes and then each of these classes are further classified into two or more classes.
