Question

For a given grouped data with 40 observations, the 'less than ogive' and the more than
ogive' intersect at (20.5, 15). The median of the data is:
(A) 4.5
(B) 20
(C) 50
(D) 15.5. and How?​

Answer 1

The median of the data is: 20.5.

Explanation:

• We know that for a when given grouped data with n observations,the "less than ogive" and "the more than ogive" intersects with each other at point (x,y) on coordinate plane.

Then, the x-coordinate gives the median of the data .

Thus , if for a given grouped data with 40 observations, the 'less than ogive' and the more than  ogive' intersect at (20.5, 15).

Then The median of the data is: 20.5

Hence, the median of the data is: 20.5.
