Answer 1

Answer:

Given :  table gives production yield in kg. per hectare of wheat of 150 farms in a village.

To find : Mean & Median  

Solution:

Class            frequency    cumlative f

50 - 53           3                  3

53 – 56         8                11

56 – 59         14                25

59 – 62         30               55

62 – 65         36               91

65 – 68         28               119

68 – 71          16                135

71 – 74          10                 145

74 – 77           5                 150

Median   lies in 62 - 65     as 150/2  = 75  is between 56 - 91

Median  = 62  +  3 (75 - 55) / 36

=  63.67

Mode lies  in 62 - 65

Mode = 62   +  3 ( 36 - 30)/(36 - 30 + 36 - 28)

= 63.29
