Question 3
The following table gives production yield per hectare of wheat of 100 farms of a village.
$\begin{matrix} P r o d u c t i o n y i e l d (i n k g / h a) & 50 - 55 & 55 - 60 & 60 - 65 & 65 - 70 & 70 - 75 & 75 - 80 N u m b e r o f f a r m s & 2 & 8 & 12 & 24 & 38 & 16 \end{matrix}$
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 -
$\begin{matrix} P r o d u c t i o n y i e l d (l o w e r c l a s s l i m i t s) & C u m u l a t i v e f r e q u e n c y m o r e t h a n o r e q u a l t o 50 & 100 m o r e t h a n o r e q u a l t o 55 & 100 - 2 = 98 m o r e t h a n o r e q u a l t o 60 & 98 - 8 = 90 m o r e t h a n o r e q u a l t o 65 & 90 - 12 = 78 m o r e t h a n o r e q u a l t o 70 & 78 - 24 = 54 m o r e t h a n o r e q u a l t o 75 & 54 - 38 = 16 \end{matrix}$
Now, taking lower class limits on x-axis and their respective cumulative frequencies on y-axis we can obtain its ogive as follows.
