Q4. What is the formula for calculating Mode?

Ans: In a grouped frequency distribution, we can find the mode by locating a class with the maximum frequency, called the modal class. The formula for calculating mode is given below:

Mode= l + (f_{1} - f_{0})/(2f_{1} - f_{0} - f_{2}) * 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.
