Determination of Median by Ogive Curves
If we join the joint of intersection of “more than” and “less than” ogive curves in a graph, the point corresponding on the x-axis gives the value of the median (Median is discussed in detail under “Measure of Central Tendency”).

Example:
The median of the above data can be calculated as:

Price of share (Rs.)No. of sharesLess than frequencyMore than frequency
