CHISQ.DIST

CHISQ.DIST(x, degrees_freedom, cumulative)

Returns the probability distribution function OR the cumulative probability function for a chi-squared distribution (left tailed).

x	The number from the distribution.
degrees_freedom	The number of degrees of freedom.
cumulative	A logical value indicating the type of function to use: False (or 0) = individual probability (equal to) True (<> 0) = cumulative probability (equal to or less than)

REMARKS

* For an illustrated example refer to the page under Distributions
* 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 numeric, then #VALUE! is returned.
* If "cumulative" = False, then the height of the curve at "x" is returned.
* If "cumulative" = True, then the area under the curve to the left of "x" is returned.
* You can use the CHISQ.DIST.RT function to return the probability distribution function for a chi-squared distribution (right tailed) (no cumulative).
* 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.
* You can use the SKEW function to return the skewness of a distribution.
* You can use the KURT function to return the kurtosis of a distribution.
* This function was added in Excel 2010 but it does not replace the CHIDIST function because this was right tailed.
