The mode of a continuous frequency distribution can be estimated using the formula: MCQ with Answer and Explanation

The mode of a continuous frequency distribution can be estimated using the formula:

A. L + [(f₀ - f₁) / (f₀ + f₁)] × h

B. L + [(f₁ - f₀) / (2f₁ - f₀ - f₂)] × h

C. L + [(f₁ - f₀) / (f₁ - f₂)] × h

D. L + (h / 2)

Answer: Option B

Solution (By JKExamLibrary)

For grouped data, mode = L + [(f₁ - f₀) / (2f₁ - f₀ - f₂)] × h, where L=lower limit of modal class, f₁=frequency of modal class, f₀=previous class frequency, f₂=next class frequency, h=class width.

Question #3 Report Error

Perinatal mortality rate per 1000 total births is 35. If there were 700 late fetal deaths and early neonatal deaths combined, the number of total births (live births + stillbirths) is:

A. 35,000

B. 24,500

C. 2,000

D. 20,000

View Answer & Solution Discuss

Correct Answer: Option D

Explanation:
Rate = (perinatal deaths / total births) × 1000 => 35 = 700 / total births × 1000 => total births = 700,000/35 = 20,000.
