To find the median from a cumulative frequency graph (also called an ogive):
1. Locate half the total cumulative frequency on the y-axis.
2. Draw a horizontal line from that value to intersect the curve.
3. From the point of intersection, draw a vertical line down to the x-axis.
4. The x-value where the vertical line touches the axis is the median.

From the graph:
• The maximum cumulative frequency is 52, so half of that is 26.
• Drawing across from 26 and down to the x-axis gives a value of approximately 15.

Correct answer: C. 15.
