The median of a given frequency distribution is found graphically with the help of
There are two ways in which median can be determined graphically.
(1) By drawing any of the ogive
In this case, we first compute , where N is the sum of frequencies and then we locate the point M corresponding to Nth cumulative frequency on curve, and the x-coordinate of M gives the median.
(2) By drawing both of the ogives
We draw both ogive curves [i.e. less than ogive and greater than ogive] and intersection of both ogives gives the value of median.
