Question

The coefficient of skewness of a distribution is 0.4. Its S.D and mean are respectively 8 and 30. The mode of the distribution is

please give step by step explanation ​

Answer 1

Answer:

Karl Pearson's coefficient of skewness =

S.D.

Mean−Mode

∴0.32=

6.5

29.6−Mode

⇒Mode=27.52 Also Karl Pearson's coeff.of skewness =

S.D

3(Mean−Median)

∵0.32=

6.5

3(29.6−Median)

⇒Median=28.91
