To find the mode of a given data set in a grouped frequency distribution, follow these steps:
1. Identify the modal class: This is the class interval with the highest frequency.
2. Use the mode formula:
{Mode} = L + {f1 - f0} ÷ {2f1 - f0 - f2} × h
where:
- ( L ) = lower boundary of the modal class
- ( f1 ) = frequency of the modal class
- ( f0) frequency of the class preceding the modal class
- ( f2 ) = frequency of the class succeeding the modal class
- ( h ) = class width
