T.DIST |
T.DIST(x, degrees_freedom, cumulative) |
Returns the probability distribution function for a t distribution (left tailed). |
x | The number from the distribution. |
degrees_freedom | The number of degress 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 t distribution is a [[continuous distribution]] * If "degrees_freedom" < 1, then #NUM! 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. * If "x" < 0, then #NUM is returned. * If "x" is not numeric, then #VALUE! is returned. * You can use the T.DIST.RT function to replace the TDIST function when "tails" = 1. * You can use the T.DIST.2T function to replace the TDIST function when "tails" = 2. * You can use the T.INV function to * You can use the T.INV.2T function to * You can use the T.TEST function to * This function was added in Excel 2010. * For the Microsoft documentation refer to support.microsoft.com * For the Google documentation refer to support.google.com |
