The following table gives production yield per hectare of wheat of 100 farms of a village:

Production yield in kg per hectare:	50-55	55-60	60-65	65-70	70-75	75-80
Number of farms:	2	8	12	24	38	16

Draw 'less than' ogive and 'more than' ogive.

Given:

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

To do:

We have to draw 'less than' ogive and 'more than' ogive.

Solution:

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

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

Plot the points (55, 2), (60, 10), (65, 22), (70, 46), (75, 84) and (80, 100) on the graph and join them in free hand to get a less than ogive.

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

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

Plot the points (50, 100), (55, 84), (60, 46), (65, 22), (70, 10), (75, 2) and (80, 0) on the graph and join them in a free hand to get a more than ogive.
