   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
