Question

Point of intersection of less than and more than type ogives of a group dat is 27 12 .total frequency
of data is

Answer 1

point of intersection of less than more than type ogives of a group data is (27, 12) .

means, the type of cumulative frequency curves, less than or more than ogives , meet at point (27, 12) .

Thus, median = x co-ordinate of the point of intersection of more than ogive and less than ogive .

here x coordinate of the point of the intersection of more than ogive and less than ogive is 27 . so,total frequency of date = median = 27.

hence, answer is 27.
