Lesson 3 of 5

The modal class is the class with the highest frequency. Mode

= l + \dfrac{f_1 - f_0}{2f_1 - f_0 - f_2}\cdot h

, where

l

= lower limit of modal class,

f_1

= frequency of modal class,

f_0

= frequency of preceding class,

f_2

= frequency of succeeding class,

h

= class width.
