Draw frequency polygon and frequency curve for the following data on land holding by the farmers: Area in hectares 11 – 20 21 – 30 31 – 40 41 – 50 51 – 60 61 – 70 71 – 80 No. of farmers 58 103 208 392 112 34 12

5. Draw frequency polygon and frequency curve for the following data on land holding by the farmers:

Area in hectares	11 – 20	21 – 30	31 – 40	41 – 50	51 – 60	61 – 70	71 – 80
No. of farmers	58	103	208	392	112	34	12

Solution:

Area in hectares	Class mark	No. of farmers
1 – 10	5.5	0
11 – 20	15.5	58
21 – 30	25.5	103
31 – 40	35.5	208
41 – 50	45.5	392
51 – 60	55.5	112
61 – 70	65.5	34
71 – 80	75.5	12
81 – 90	85.5	0
