Question

For a given observations the lesss than ogive and the more than ogive interesect at (38.5,34).What are the total numbers io observations

Answer 1

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.
