Question 3
The following table gives production yield per hectare of wheat of 100 farms of a village.

Production yield (in kg/ha)505555606065657070757580Number of farms2812243816
Change the distribution to a more than type distribution and draw its ogive.

Solution

We can obtain cumulative frequency distribution of more than type as following -
Production yield(lower class limits)Cumulativefrequencymore than or equal to 50100more than or equal to 551002=98more than or equal to 60988=90more than or equal to 659012=78more than or equal to 707824=54more than or equal to 755438=16
Now, taking lower class limits on x-axis and their respective cumulative frequencies on y-axis we can obtain its ogive as follows.
