The following table gives production yield per hectare (in quintals) of wheat of

100

farms of a village. Change the distribution to a 'more than' type distribution and draw its ogive.

Production yield per hectare (in quintals) of wheat of 100 farms
Production yield/hect.	40-45	45-50	50-55	55-60	60-65	65-70
No. of farms	4	6	16	20	30	24

Answer

The 'more than' cumulative frequencies are: more than

40 \to 100

, more than

45 \to 96

, more than

50 \to 90

, more than

55 \to 74

, more than

60 \to 54

, more than

65 \to 24

. Plotting these against the lower limits and joining gives a falling ogive (see figure).
