Question

46. 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) 36.0
(b) 20.5
(c) 15.5
(d) 5.5
(Board Term-I, 2013)​

Answer 1

Answer:

20.5

Step-by-step explanation:

The less than ogive curve gives cumulative frequency (probability) for x <= a.

The more than ogive curve gives cumulative frequency (probability) for x >= a.

They intersect exactly at the median, as cumulative frequency will be 50% of the total at median.
