What is mode ? State the formula of mode for grouped frequency distribution.

Explanation

mode `=(f_m^- ""f_(m-1))/(2f_m""f_(m-1)-f_(m+1))xxh` [ where l = lower class - limit of the class containint the mode, `f_m` = frequency of that class, `f_(m-1)` = frequency of its previous class, `f_(m+1)` = frequency of its next class and h = class - length,]
