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

Description

The Excel BETA.DIST function returns the beta distribution. So you can use the BETA.DIST 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.

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

The BETA.DIST function is available in Excel 2016, Excel 2013, Excel 2010, Excel 2011 for Mac.

Syntax

The syntax of the BETA.DIST function is as below:

= BETA.DIST(x, alpha, beta, cumulative, [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.
• Cumulative – This is a required argument. It is a logical value that specifies the type of distribution to be used. If the cumulative is TRUE, the BETA.DIST function returns the cumulative distribution function; if it is equal to FALSE, the BETA.DIST function returns the probability density function.
• 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 BETA.DIST function will return the #VALUE! Error.
• If the Alpha or Beta argument is smaller than or equal to 0, then the BETA.DIST function will return #NUM! Error.
• If the argument X is small than A and greater than B, the BETA.DIST function will Return #NUM! Error.

Excel BETA.DIST Function Examples

The below examples will show you how to use Excel BETA.DIST Function to calculate the cumulative beta distribution or beta probability density function.

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

=BETA.DIST(3,5,10,TRUE,1,4)

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

=BETA.DIST(3,5,10,FALSE,1,4)
