# CHISQ.DIST

Returns the chi-squared distribution.

The chi-squared 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

CHISQ.DIST(<x>, <deg_freedom>, <cumulative>)


### Parameters

Term Definition
x The value at which you want to evaluate the distribution.
Deg_freedom The number of degrees of freedom.
cumulative A logical value that determines the form of the function. If cumulative is TRUE, CHISQ.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.

## Return value

The chi-squared distribution.

## Remarks

• If x or deg_freedom is nonnumeric, an error is returned.

• If deg_freedom is not an integer, it is rounded.

• If x < 0, an error is returned.

• If deg_freedom < 1 or deg_freedom > 10^10, an error is returned.

• This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

## Example

The following DAX query,

EVALUATE { CHISQ.DIST(2, 2, TRUE) }


Returns

[Value]
