Gross Reproduction Rate (GRR) differs from TFR by:
A. Using a different age range for women
B. Expressing rate per 100 women instead of 1,000
C. Including only female births in the numerator
D. Adjusting for infant mortality
Answer: Option C
Solution (By JKSSB Mock Tests)
GRR = Σ (ASFR for female births only) × 5 (for 5-year age groups), measuring the average number of daughters a woman would have, focusing on female offspring for generational replacement analysis.
Assertion (A): For a moderately skewed distribution, mean – mode ≈ 3(mean – median). Reason (R): In any skewed distribution, the median always lies between the mean and mode. Choose the correct option:
A.A is true, R is false
B.Both A and R are true, but R is not the correct explanation of A
C.A is false, R is true
D.Both A and R are true, and R is the correct explanation of A
Explanation:
The empirical relationship (A) is true for moderate skewness. In skewed distributions, median lies between mean and mode, but this fact does not directly explain the formula; it's an observed pattern.
