It is assumed that the frequency of each class- in this way and continue as before (i e , find f i u i and 2 = frequency of the class succeeding the modal class
the Modal class 0 = frequency of class interval just before the Modal class c f = cumulative frequency of the class before the median class h = class size
The mean, median and mode are all valid measures of central tendency, but under different and F0 = Frequency corresponding to the pre-modal class
1) If the very first class of the frequency distribution is the'modal class, the fo is taken as drawn by using only three classes - pre-modal, modal and post-modal
