## Kurtosis Excel Calculator

This Excel spreadsheet calculates kurtosis, skewness, standard deviation, and other summary statistics for a data set you enter. Simply copy-paste your data (order doesn’t matter) into the column marked in the file, choose population or sample, and see the result.

The Calculator also contains several charts where you can evaluate kurtosis and the other measures visually and you can compare your data to normal distribution (which has kurtosis of 3 = zero excess kurtosis).

## Calculating Kurtosis in Excel

There is a built in function for calculating kurtosis in Excel: **KURT**. This function actually calculates **sample excess kurtosis**. There are no built-in functions for calculating the other forms of kurtosis (population kurtosis, sample kurtosis, population excess kurtosis), but you can calculate them by adjusting the result of KURT manually – see detailed instructions here: Calculating Kurtosis in Excel. Alternatively, you can calculate them directly using the formulas below.

The different ways how to calculate each form of kurtosis in Excel are demonstrated in practice in the second Excel file that comes with the Summary Statistics Calculator (Summary_Statistics_Manual.xlsx, where you can see the exact formulas applied in Excel).
