# BETADIST Function in Excel – BETA Distribution in Excel

BETADIST Function in Excel calculates the cumulative beta probability density function for a supplied set of parameters.

#### Syntax of BETADIST Function in Excel:

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

• X -The value at which the function is to be calculated (must be between [A] and [B]).
• alpha -A parameter of the distribution (must be > 0).
• beta -A parameter of the distribution (must be > 0).
• [A] -An optional argument with default value 0, which gives the lower bound of the interval of x.
• [B] -An optional argument with default value 1, which gives the upper bound of the interval of x.

#### Example of BETADIST Function in Excel

##### Formula

• Beta Distribution function BETADIST is supplied values from 0 to 1 on interval of 0.1 along with alpha value as 6 and beta value as 8.

So the result will be cumulative beta probability density function ranging from 0 to 1 as shown below.

##### Result

Cumulative Beta Distribution of x ranging from 0 to 1 with alpha =6 and beta=8 is plotted below
