# CHIDIST

CHIDIST(x, degrees_freedom)

Returns the probability distribution function for a chi-squared distribution (right tailed) (no cumulative).

 x The number from the distribution. degrees_freedom The number of degrees of freedom.

 REMARKS
 * CHISQ.DIST.RT was added in Excel 2010 to replace this function and include an option for cumulative probability.* The chi-squared distribution is a [[continuous distribution]]* If "x" < 0, then #NUM! is returned.* If "x" is not numeric, then #VALUE! is returned.* If "degrees_freedom" is not an integer, it is truncated.* If "degrees_freedom" < 1, then #NUM! is returned.* If "degrees_freedom" = 10^10, then #NUM! is returned.* If "degrees_freedom" is not numeric, then #VALUE! is returned.* All the values are greater than zero.* This function uses the following formula P(X>x), where X is a ?2 random variable ???* You can use the CHISQ.DIST function to return the probability distribution function OR the cumulative probability function for a chi-squared distribution (left tailed).* You can use the CHISQ.INV function to return the inverse of the probability distribution function for a chi-squared distribution (left tailed).* You can use the CHISQ.INV.RT function to return the inverse of the probability distribution function for a chi-squared distribution (right tailed) (no cumulative).* You can use the CHISQ.TEST function to return the probability value from a chi-squared distribution.* For the Microsoft documentation refer to support.microsoft.com* For the Google documentation refer to support.google.com
