how one can find median of a frequency distribution graphically
Answers
When you have only one (either less than or more than cumulative) curve:
One obvious way is to locate on n/2 (n is the total number of observations) on the y axis. From this point draw a line parallel to x axis cutting the curve at a point.
From this point drop a line parallel to y axis onto the x axis. That gives the median (check the attachment)
Another way of obtaining the median:
When both the curves are given then drop a perpendicular onto the x axis from the point of intersection of both the curves. That point gives you the median.

Step-by-step explanation:
It is possible to obtain the median of grouped data graphically using the ogive (both less than and more than cumulative).
