Answer» Answer: In symmetrical distribution the MEAN and mode coincide But in skewed distribution , they don’t and hence the DIFFERENCE between them measures the amount of skewness Measure of skewness = Mean – Mode Coefficient of skewness ; SKp = Mean – Mode  However if Mode is ill – defined , we make use of empirical relationship between Mean – Median – Mode Mean – Mode = 3(Mean – Median) In that CASE SKp = 3(Mean – Median)  I Think it is the right answer.

Answer»

Answer:

In symmetrical distribution the MEAN and

mode coincide

But in skewed distribution , they don’t and

hence the DIFFERENCE between them

measures the amount of skewness

Measure of skewness = Mean – Mode

Coefficient of skewness ;

SKp = Mean – Mode



However if Mode is ill – defined , we make

use of empirical relationship between Mean –

Median – Mode

Mean – Mode = 3(Mean – Median)

In that CASE SKp = 3(Mean – Median)



I Think it is the right answer.
