The FDIST function calculates the probability distribution (right-tailed) for two data sets. It's commonly used to determine if two data sets have different variances. The parameters used in this function include the value to evaluate and the degrees of freedom for the numerator and denominator.

Guide on How to Use FDIST Function in Excel - Illustrated Examples
Syntax: FDIST(x, deg_freedom1, deg_freedom2)
Where:
- X : Mandatory – Represents the value to evaluate.
- Deg_freedom1 : Mandatory – Denotes the degrees of freedom in the numerator.
Illustrative Example
Consider a spreadsheet with real values corresponding to FDIST function parameters. In this example, we compute with the value to evaluate as 25, degrees of freedom in the numerator as 4, and degrees of freedom in the denominator as 3:
Enter the probability distribution formula in cell C9. The calculated result of the function is 0.012209822:
Now you're familiar with using the FDIST function in Excel. When performing calculations with this function, the value of x must be a positive number, and if the degrees of freedom values are not integers, they will be automatically converted to integers for result calculations. You can apply the FDIST function in Excel across Office versions 2003, 2007, 2010, and 2013.
In addition to the above function, you can also explore the PERCENTILE function in the article PERCENTILE Function for a deeper understanding and easy application in your work.
