Question

If less than and more than ogive intersect at the point (27, 34), then find the median of the distributions and also find the total number of observations.

Answer 1

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.

So median is  20.5

Answer 2

Answer:

answer is 27

Step-by-step explanation:

The less than ogive curve gives C.f for x which is less than or equal to 'a'

Similarly,

the more than ogive curve gives C.f for x which is greater than or equal to 'a'

They intersect exactly at median

So the abscissa will be taken as the median

Which is 27
