Topics Covered in Exercise 13.2 Class 10 Mathematics Questions

In ex 13.2, the questions are related to the topic mode of the grouped data, which is the most important part of this ex. You can get the full explanation of this topic below.


Mode of Grouped Data

  1. Mode of Grouped Data - The number that occurs most often in the series is referred to as the mode of the n numbers.

In the ungrouped data, the most frequence no is the mode of sequence, but in the grouped data, we can only find the class interval that has the max frequency number, i.e. the modal class.

The mode value in the modal class is determined by:

                     Mode = 1 + f1 - f0/2f1 - f0 - f2 ⨯ h

Where,   l = lower limit of the modal class,

              h = size of the class interval (assuming all class sizes to be equal),

              f 1 = frequency of the modal class, 

              f 0 = frequency of the class preceding the modal class,

              f 2 = frequency of the class succeeding the modal class.
