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) = [[probability distribution function]] (equal to) True (<> 0) = [[cumulative probability function]] (equal to or less than) |
REMARKS |
* 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. * For the Microsoft documentation refer to support.microsoft.com * For the Google documentation refer to support.google.com |
