The following table gives production yield per hectare of wheat of 100 farms of a village.
Production yield in kg per hectare:50-5555-6060-6565-7070-7575-80
Number of farms:2812243816

Change the distribution to a more than type distribution

Given:

The given table gives production yield per hectare of wheat of 100 farms of a village.

To do:

We have to change the distribution to a more than type distribution, and draw its ogive.

Solution:

We first prepare the cumulative  frequency distribution table by more than one method as given below:

Production Yield in kg per hectareNumber of farms
More than or equal to 50100
More than or equal to 55
100-2 = 98
More than or equal to 60
98-8= 90
More than or equal to 65
90-12=78
More than or equal to 70
78-24=54
More than or equal to 75
54-38 =16

Represent Lower class limits along X-axis and cumulative frequency along Y-axis.

Plot the points (50, 100), (55, 98), (60, 90), (65, 78), (70, 54) and (75, 16) on the graph and join them in a free hand to get a more than ogive.
