Calculate Coefficient of Skewness (SK)





Formula

The formula to calculate the Coefficient of Skewness (SK) is:

\[ SK = 3 \times \frac{M - MD}{s} \]

What is the Coefficient of Skewness?

The coefficient of skewness is a method developed to find the relative skewness in a sample using the mean and median. Skewness itself is a measure of the shape of a data set. In other words, it is a measure of how close the mean and median are to each other relative to the sample size.

Example Calculation

Let's consider an example:

Using the formula to calculate the Coefficient of Skewness:

\[ SK = 3 \times \frac{50 - 45}{10} = 3 \times 0.5 = 1.5 \]

This means that the coefficient of skewness for this scenario is 1.5.
