Question

For a given data with 40 observations the less than ogive and the more than ogive interest at (20.5,15). The median of the data is:

• A. 5.5
• B. 20.5
• C. 15
• D. 40

Answer 1

The correct option is B 20.5

The ogive is the free hand graph.

The abscissa of the intersection of the less than ogive and more than ogive gives the median of the data.

Given that the intersection point is $(20.5,15)$. The abscissa i.e., X-coordinate is the median.

Therefore the median is $20.5$
