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.

## Syntax

``````BETA.DIST(x,alpha,beta,cumulative,[A],[B])
``````

#### Parameters

TermDefinition
xThe value between A and B at which to evaluate the function
AlphaA parameter of the distribution.
BetaA parameter of the distribution.
AOptional. A lower bound to the interval of x.
BOptional. An upper bound to the interval of x.

## Return Value

Returns the beta distribution.

## Remarks

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.
