In this exercise, students will solve questions based on finding the mode of grouped data along with finding the mean value. In a grouped frequency distribution, we cannot find the mode with the help of given frequencies but we can locate a class with the maximum frequency, called the modal class. The mode is a value inside the modal class and its formula is;
where l = lower limit of the modal class,
h = size of the class interval (assuming all class sizes to be equal),
f1 = frequency of the modal class,
f0= frequency of the class preceding the modal class,
f2= frequency of the class succeeding the modal class.
