## GAMMADIST Excel Syntax and Functionality

Searching to learn new Excel formulae? Maybe heard of the **GAMMADIST** function? It’s strong for data analysis on Excel. In this text, let’s check out the GAMMADIST syntax and features. We’ll break it down into parts you can grasp. First, we’ll explore the **GAMMADIST** Excel syntax. Then, we’ll cover the arguments with **GAMMADIST**. By the end, you’ll understand how to use **GAMMADIST** in Excel sheets.

### Understanding the Syntax of GAMMADIST: Excel Formula

**GAMMADIST** Excel Function is used to calculate the **Gamma Distribution** of a data set.

When writing in Excel syntax format, ‘**x**‘ represents the value to find the distribution for. ‘**Alpha**‘ is the shape parameter and ‘**beta**‘ is the scale parameter. Choose whether or not to use Cumulative.

Knowing how to write it correctly is essential for accurate results.

Did you know that **Gamma distribution** was discovered by mathematician Legendre in 1808? Then, Adolphe Quetelet rediscovered it and **named it in 1825** due to his research on probability theory.
