Question

for a Frequency Distribution:
Q3-Q2=40 Q2-Q1 = 60.
Find Coefficient of skewness​

Answer 1

Answer:

$-0.5$.

Step-by-step explanation:

We have given the frequency distributions are Q3-Q2=40 and Q2-Q1=60.

Find the Bowley’s coefficient of skewness :

$SK_{B} =\frac{(Q3- Q2) - (Q2-Q1)}{(Q3-Q2) + (Q2 - Q1)} }$

Substitute the value of Q3-Q2=40 and Q2-Q1=60 in the above formula.

$=\frac{40-60}{40+60}\\ =\frac{-20}{100}\\ =-0.5$

The solution of the coefficient of skewness is $-0.5$.

Answer 2

Step-by-step explanation:

We have given the frequency distributions are Q3-Q2=40 and Q2-Q1=60.

Find the Bowley’s coefficient of skewness :

SK_{B} =\frac{(Q3- Q2) - (Q2-Q1)}{(Q3-Q2) + (Q2 - Q1)} }

Substitute the value of Q3-Q2=40 and Q2-Q1=60 in the above formula.

\begin{gathered}=\frac{40-60}{40+60}\\ =\frac{-20}{100}\\ =-0.5\end{gathered}

=

40+60

40−60

=

100

−20

=−0.5

The solution of the coefficient of skewness is -0.5 there for this have negative
