CHISQ.INV Function (DAX)

Owen Duncan|Last Updated: 5/22/2018

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.

Syntax

CHISQ.INV(probability,deg_freedom)  

Parameters

TermDefinition
ProbabilityA probability associated with the chi-squared distribution.
Deg_freedomThe number of degrees of freedom.

Return Value

Returns the inverse of the left-tailed probability of the chi-squared distribution.

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 rounded.

If deg_freedom < 1 or deg_freedom > 10^10, CHISQ.INV returns the #NUM! error value.
