For a distribution, mean = 100, mode = 127 and SD = 60. Find the Pearson coefficient of skewness Sk_{p}.

###### Advertisements

#### Solution

Given, Mean = 100, Mode = 127, S.D. = 60

Pearsonian coefficient of skewness,

Sk_{p} = `("Mean"-"Mode")/"S.D."`

= `(100 - 127)/(60)`

= `(-27)/(60)`

= − 0.45
