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.
