Question

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

Production yield (in kg\ha)	$50-55$	$55-60$	$60-65$	$65-70$	$70-75$	$75-80$
Number of farms	$2$	$8$	$12$	$24$	$38$	$16$

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

Answer 1

First we have to convert the give distribution to More than cumulative frequency distribution:

Production yield (in kg\ha)	Number of farms
$>50$	$100$
$>55$	$100-2=98$
$>60$	$98-8=90$
$>65$	$90-12=78$
$>70$	$78-24=54$
$>75$	$54-38=16$

Now, draw the ogive by plotting the points $(50,100),(55,98),(60,90),(65,78),(70,54)$ and $(75,16)$ on this graph paper and join them by a free hand smooth curve.
