Given : आवृत्तिः 3 6 9 13 8 5 4

पदः 6 7 8 910 11 12

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
