उत्तर
The median of a frequency distribution is found graphically with the help of ogives.
Explanation:
An ogive is a cumulative frequency curve (or polygon). To find the median graphically you mark `N/2` on the cumulative-frequency (y) axis, draw a horizontal line to the ogive, then drop a perpendicular to the x-axis, the x-value where it meets is the median.
