Question 1174732
To find the coefficient of skewness using quartiles, we use Bowley's coefficient of skewness (also known as the quartile coefficient of skewness). The formula is:

Coefficient of Skewness = (Q3 - 2 * Q2 + Q1) / (Q3 - Q1)

Where:
* Q1 is the first quartile
* Q2 is the second quartile (median)
* Q3 is the third quartile

Given:
* Q1 = 37.15
* Q2 = 49.21
* Q3 = 61.27

Let's calculate:

1.  Calculate (Q3 - 2 * Q2 + Q1):
    * 61.27 - 2 * 49.21 + 37.15 = 61.27 - 98.42 + 37.15 = 0

2.  Calculate (Q3 - Q1):
    * 61.27 - 37.15 = 24.12

3.  Calculate the coefficient of skewness:
    * 0 / 24.12 = 0

Therefore, the coefficient of skewness is 0.
