Correct Answer Explanation
Religion, caste, or gender (qualitative attributes) can be represented by bar diagrams but NOT by histograms.
Key Points:
- Histograms require continuous quantitative data.
- Bar diagrams can handle discrete variables and qualitative attributes.
- Discrete variables like family size, spots on dice, and attributes like gender can use bar diagrams only.
- Continuous variables like height, wages can use both bar and histogram.
Why Other Options Are Wrong
- A. Height: Continuous variable — can be shown in both.
- B. Daily wages: Continuous variable — can be shown in both.
- D. Marks: Can be treated as continuous — can be shown in both.
