This post will guide you how to use the BETADIST function with syntax and examples in Microsoft excel.

Description

The Excel BETADIST function returns the cumulative beta probability density function. So you can use the BETADIST function to calculate the cumulative beta distribution for a given set of parameters in Excel. And the beta distribution is used to study variation in the percentage of something across samples. And this function has been replaced by BETA.DIST function.

The BETADIST function is a build-in function in Microsoft Excel and it is categorized as a Statistical Function.

The BETADIST function is available in Excel 2016, Excel 2013, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000, Excel 2011 for Mac.

Syntax

The syntax of the BETADIST function is as below:

= BETADIST(x, alpha, beta, [A], [B])

Where the BETA.DIST function arguments are:

• X -This is a required argument.  The value that is between A and B at which the function is to be calculated.
• Alpha – This is a required argument.  It is a parameter of the distribution.
• Beta – This is a required argument.  It is a parameter of the distribution.
• A – This is an optional argument. A lower bound to the interval of x. If it is omitted, it will be set the default value 0.
• B – This is an optional argument. A upper bound to the interval of x. If it is omitted, it will be set the default value 1.

Note:

• If any argument is non-numeric, the BETADIST function will return the #VALUE! Error.
• If the Alpha or Beta argument is smaller than or equal to 0, then the BETADIST function will return #NUM! Error.
• If the argument X is small than A and greater than B, the BETADIST function will Return #NUM! Error.

Excel BETADIST Function Examples

The below examples will show you how to use Excel BETADIST Function to calculate the cumulative beta distribution.

1# to calculate the cumulative beta probability density function for a supplied set of parameters, using the following formula:

=BETADIST(3,5,10,1,4)
