Question

A frequency distribution is as follows:

Value Frequency

At least 0, under 5 2

At least 5, under 8 30

At least 8, under 11 10

At least 11, under 14 4

At least 14, under 17 2

Calculate quartile measure of skewness.​

Answer 1

Answer:

Step-by-step explanation:

To find quartile

N/2 = 48 /2 = 24

Median = L + (n/2 -c)×h / f

= 5 + 24-2 ×3/30

= 5 + 22×3/30

= 7.2

Now to find Q1

N /4 = 48 /4 = 12

Q1 = L + (n/4 -c)×h / f

Q1 = 2 + 12-0 ×3/2

Q1 = 2 +36 /2

Q1= 2 + 18

Q1 = 20
