To Find : कार्ल पियर्सन का विषमता गुणांक
Karl Pearson's coefficient of skewness
Solution:
x f cf xf
6 3 3 18
7 6 9 42
8 9 18 72
9 13 31 117
10 8 39 80
11 5 44 55
12 4 48 48
48 432
48/2 = 24 ( between 18 and 31 ) => median = 9
Mean = ∑xf/∑f = 432/48 = 9
Karl Pearson's coefficient of skewness = 3 ( Mean - Median ) / sd
As mean and median are same
so कार्ल पियर्सन का विषमता गुणांक = 0
Karl Pearson's coefficient of skewness = 0
