# 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
 * This function was added in Excel 2010.* 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* For the Microsoft documentation refer to support.microsoft.com* For the Google documentation refer to support.google.com
