Your answer

Answer 1

Answer:

Sk

b

is Bowley's coefficient of skewness,

where Q

2

is the median and

Q

1

&Q

3

are the lower and upper quartiles respectively.

Sk

b

=

(Q

3

−Q

2

)+(Q

2

−Q

1

)

(Q

3

−Q

2

)−(Q

2

−Q

1

)

⇒Sk

b

=

90+120

90−120

⇒Sk

b

=

210

−30

⇒Sk

b

=−0.142

So, it is a negatively skewed distribution.
