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

Production yield

50 - 55

55 - 60

60 - 65

65 - 70

70 - 75

75 - 80

Number of farms

2

8

12

24

38

16

We can obtain cumulative frequency distribution of more than type as following: 

Production yield

(lower class limits)

Cumulative frequency

More than or equal to 50

100

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

 

Now, taking lower class limits on x-axis and their respective cumulative frequencies on y-axis, we can obtain the ogive as follows.
