# CHIDIST

CHIDIST(x, degrees_freedom)

Returns the probability of getting less than or equal to a particular value in a chi-squared distribution (right tailed).

 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.* 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 ???* For the Microsoft documentation refer to support.microsoft.com
