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 + (h / 2)

B. L + [(f₀ - f₁) / (f₀ + f₁)] × h

C. L + [(f₁ - f₀) / (f₁ - f₂)] × h

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

Answer: Option D

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.
