BETA.DIST DAX Function (Statistical)

Returns the beta distribution. The beta distribution is commonly used to study variation in the percentage of something across samples, such as the fraction of the day people spend watching television.


BETA.DIST ( <X>, <Alpha>, <Beta>, <Cumulative> [, <A>] [, <B>] )
Parameter Attributes Description

The value between A and B at which to evaluate the function.


A parameter of the distribution.


A parameter the distribution.


A logical value that determines the form of the function. If cumulative is TRUE, BETA.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.

A Optional

A lower bound to the interval of x.

B Optional

An upper bound to the interval of x.

Return values

Scalar A single decimal value.

Returns the beta distribution.


If any argument is nonnumeric, BETA.DIST returns the #VALUE! error value.

If any argument is not an integer, it is rounded.

If alpha ≤ 0 or beta ≤ 0, BETA.DIST returns the #NUM! error value.

If x < A, x > B, or A = B, BETA.DIST returns the #NUM! error value.

If you omit values for A and B, BETA.DIST uses the standard cumulative beta distribution, so that A = 0 and B = 1.
