# CHISQ.DIST function

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)

The CHISQ.DIST function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

**X**Required. The value at which you want to evaluate the distribution.**Deg_freedom**Required. The number of degrees of freedom.**Cumulative**Required. 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.

## Remarks

- If any argument is nonnumeric, CHISQ.DIST returns the #VALUE! error value.
- If x is negative, CHISQ.DIST returns the #NUM! error value.
- If deg_freedom is not an integer, it is truncated.
- If deg_freedom < 1 or deg_freedom > 10^10, CHISQ.DIST returns the #NUM! error value.
