# Calculate Skewness in Excel

You need to calculate the skewness of a dataset in Excel.

## Step-by-step tutorial

Excel supports two different functions for skewness: SKEW.P for populations, and SKEW for samples. The syntax is the same for both, so we'll focus on SKEW.P.

Let's use the Titanic dataset, which contains the list of passengers for the ill-fated voyage. We'll measure the skewness of the age variable.

First we use Excel's Filter feature (Data > Filter) to filter out values where the age is unknown (i.e., filter out the ? entries).

Now we apply the SKEW.P function to the age column to calculate its skewness:
