# CHISQ.INV

### Definition

Returns the inverse of the left-tailed probability of 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.

### Sample Usage

### Syntax

CHISQ.INV(probability,deg_freedom)

The CHISQ.INV function syntax has the following arguments:

Probability Required. A probability associated with the chi-squared distribution.

Deg_freedom Required. The number of degrees of freedom.

### Remarks

If argument is nonnumeric, CHISQ.INV returns the #VALUE! error value.

If probability < 0 or probability > 1, CHISQ.INV 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.INV returns the #NUM! error value.
