# CHISQ.INV.RTDAX Function (Statistical)

Returns the inverse of the right-tailed probability of the chi-squared distribution. If probability = CHISQ.DIST.RT(x,…), then CHISQ.INV.RT(probability,…) = x. Use this function to compare observed results with expected ones in order to decide whether your original hypothesis is valid.

## Syntax

CHISQ.INV.RT ( <Probability>, <Deg_freedom> )
Parameter Attributes Description
Probability

A probability associated with the chi-squared distribution.

Deg_freedom

The number of degrees of freedom.

## Return values

Scalar A single decimal value.

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

## Remarks

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

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

If deg_freedom is not an integer, it is rounded.

If deg_freedom < 1, CHISQ.INV.RT returns the #NUM! error value. Given a value for probability, CHISQ.INV.RT seeks that value x such that CHISQ.DIST.RT(x, deg_freedom) = probability. Thus, precision of CHISQ.INV.RT depends on precision of CHISQ.DIST.RT. CHISQ.INV.RT uses an iterative search technique. If the search has not converged after 64 iterations, the function returns the #N/A error value.
