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.
