You can use the **Skewness Calculator** in order to derive the Skewness. Each value entered in the calculator should be separated by a comma. Example is included below.

Enter Values (each value separated by comma):

## How to use the Skewness Calculator

Let's suppose that your goal is to calculate the Skewness, given the following values:

** 2, 7, 15, 4, 8 **

To start, enter the values in the Skewness calculator, and then click on the '**Calculate Skewness**' button:

You'll then get the Skewness of **0.61439**:

## How to Manually Calculate the Skewness

You can manually derive the Skewness using this formula:

` Σ(xi - x̅)`^{3}
Skewness = (n-1)(SD^{3})

Where:

- x̅ = Mean (average of all data points)
- xi = Value of each data point
- n = Sample size
- SD = Standard Deviation

For example, let's say that you'd like to derive the Skewness, given the following values:

**2, 7, 15, 4, 8 **

Here are the calculations needed in order to get the Skewness:

- x̅ = (2+7+15+4+8) / 5 =
**7.2** - Σ(xi - x̅)
^{3}= (2-7.2)^{3}+ (7-7.2)^{3}+ (15-7.2)^{3}+ (4-7.2)^{3}+ (8-7.2)^{3}=**301.68** - n =
**5** - SD = [Σ(xi - x̅)
^{2 }]^{0.5}/ (n-1)^{0.5}= [98.8]^{0.5}/ (5-1)^{0.5}=**4.970**

Σ(xi - x̅)^{3}301.68 Skewness = (n-1)(SD^{3}) = (5-1)(4.970^{3}) = 0.61439

You'll then get the Skewness of **0.61439**.
