How to Calculate Skewness in Excel?

You can calculate skewness in Excel using the SKEW function. This function takes a range of data as input and returns the skewness coefficient.

Here's how to use the SKEW function:

1. Select the cell where you want to display the skewness coefficient.
2. Type the following formula in the selected cell:

   =SKEW(data_range)

   Replace data_range with the actual range of cells containing your data.

3. Press Enter. Excel will calculate and display the skewness coefficient.

Example:

Let's say your data is in cells A1 to A10. To calculate the skewness of this data, you would use the following formula:

=SKEW(A1:A10)

Interpreting Skewness:

• Positive skewness indicates a distribution with a longer tail on the right side. This means that there are more extreme values on the higher end of the data.
• Negative skewness indicates a distribution with a longer tail on the left side. This means that there are more extreme values on the lower end of the data.
• Zero skewness indicates a symmetrical distribution.

Practical Insights:

• Skewness is a useful measure for understanding the shape of a distribution.
• It can help identify outliers and potential data errors.
• It can be used to compare different distributions.
