To compute the probability associated with a chi-square text, use the **CHIDIST** function. Given the value of chi-square and degrees of freedom, CHIDIST returns the probability.

Note that you would expect **CHITEST** to yield the value of chi-square. It does not. It returns the value of the probability associated with the chi-square and is identical to **CHIDIST**.
