  • The following table gives production yield in kg per hectare of wheat of 100 farms of a village : Production yield(kg/hect

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

Production yield(kg/hectare): 40-45 45-50 50-55 55-60 60-65 65-70
Number of farms: 4 6 16 20 30 24

Change the distribution to a ‘more than type’ distribution, and draw its ogive.

Production yield(kg/hectare) 40-45 45-50 50-55 55-60 60-65 65-70
No.of farms,(f) 4 6 16 20 30 24
C.F.(ogive) 100 100-4=96 96-6=90 90-16=54 74-20=54 54-30=24

Given no.of farms = N= \sum f= 100
\rightarrow Now plot production field on X- axis and C.F(cumulative frequency) On y-axis


\rightarrow Cumulative frequency tells us about the no of farms
Note \rightarrow in more than type \rightarrow we take lower values of class to plot graph on X- axis
