Matching Demographic Concepts
This question requires matching key demographic concepts (Ratio, Rate, Percentage, Probabilities) with specific statistical indicators.
Correct List I & List II Matches
The correct pairings are determined as follows:
- A. Ratio is matched with I. Death Rate.
- B. Rate is matched with III. Sex Ratio.
- C. Percentage is matched with IV. Literacy Rate.
- D. Probabilities is matched with II. Maternal Mortality Rate.
Key Correlations
- Death Rate (I) is considered a Ratio (A).
- Sex Ratio (III) is considered a Rate (B).
- Literacy Rate (IV) is expressed as a Percentage (C).
- Maternal Mortality Rate (II) relates to Probabilities (D).
Final Answer Selection
The combination reflecting these matches is A-I, B-III, C-IV, D-II.
