Question

Point of intersection of less than and more than ogive is 14.5,20 then find the median

Answer 1

By the rules of the ogive ;

• Both the types of ogive less than and more than type of the same data can only interest at one point on the graph say (x,y)

• Where x = the median and y = the cumulative frequency associated with it or N/2 where N = Σfi

• Thus median of the given data = 14.5 as both its ogive intersects at (14.5,20)
