Question

Find the Mode for the following frequency distribution class Interval - 

Answer 1

Mode is the one which has the highest frequency

Here the class 30−40 has the highest frequency 16

Modal class is 30−40

Lower boundary of modal class is l = 30

Height of each class is h = 10 − 0 = 10

modal frequency is f_m = 16

Frequency of class preceding to Modal class is f₁ = 10

Frequency of class succeeding to Modal class is f₂ = 12
