Continuous distribution

Continuous distribution

    Example 13
    • For the frequency distribution of weights of sorghum ear-heads given in table below.
    Calculate the Geometric mean
    Weights of ear heads ( in g) No of ear heads (f)
    60-80 22
    80-100 38
    100-120 45
    120-140 35
    140-160 20
    Total 160

    Solution
    Weights of ear heads ( in g) No of ear heads (f) Mid x Log x f log x
    60-80 22 70 1.845 40
    59
    80-100 38 90 1.954 74.25
    100-120 45 110 2.041 91.85
    120-140 35 130 2.114 73.99
    140-160 20 150 2.176 43.52
    Total 160 324.2
    Here n = 160
