Question

If the 'less than type' ogive and 'more than type' ogive intersect each other at (20.5,15.5) then the median of the given data is

(a) 5.5 (b) 15.5 (c) 20.5 (d) 36.0

Answer 1

Given, the point of intersection of both less than and more than type ogive is (20.5, 15.5). Now, from this point draw a line perpendicular to x-axis and point at which it cuts the x-axis is the required median of the given data.

Thus, 20.5 is the required median.
