Let us carefully understand step by step:
- Step 1: In statistics, to find the median graphically, we draw two types of cumulative frequency curves:
- Less-than type cumulative frequency curve.
- More-than type cumulative frequency curve.
- Step 2: These two curves usually cut (intersect) each other at one point.
- Step 3: The x-coordinate (abscissa) of this intersection point represents the median of the data.
- Step 4: The median is the middle value of the data when all values are arranged in order. It divides the data into two equal parts.
Therefore: The abscissa of the intersection point gives the median.
Correct answer = (B).
