Question

For a given set of data, less than type ogive and more than type ogive intersect each other at the point (66.5, 30), then the sum of all frequencies in the given data is : *

Answer 1

Given: For 60 observation the 'less than type ogive' and 'more than type ogive' intersect at point (66.5 ,30 ).

To find: Median?

Solution:

• We have given total of 60 observations and 'less than type ogive' and 'more than type ogive' intersect at point (66.5 ,30 ).

• Now we know that the ogive is considered as free hand graph.  

• Median of the given data can be found out as:

                intersection of the less than ogive and more than ogive of the abscissa.

• So the intersection point is given as (66.5 ,30).

• So therefore the abscissa which is x - coordinate will be the median.

• So the median is 66.5 respectively.

Answer:

          So the median is 66.5 respectively.
