T.INV

T.INV(probability, degrees_freedom)

Returns the inverse of the probability distribution function for a t distribution (left tailed)

probability	The probability associated with the distribution.
degrees_freedom	The number of degrees of freedom.

REMARKS

* For an illustrated example refer to the page under Distributions
* The t distribution is a continuous distribution
* This function only returns the left tail of the distribution.
* If "probability" <= 0, then #NUM! is returned.
* If "probability" > 1, then #NUM! is returned.
* If "probability" is not numeric, then #VALUE! is returned
* If "degrees_freedom" < 1, then #NUM! is returned.
* If "degrees_freedom" is not an integer then it is truncated.
* If "degrees_freedom" is not numeric, then #VALUE! is returned.
* You can use the T.DIST function to return the probability distribution function for a t distribution (left tailed).
* You can use the T.DIST.2T function to return the probability distribution function for a two tailed distribution (no cumulative).
* You can use the T.DIST.RT function to return the probability distribution function for a two tailed distribution (no cumulative).
* You can use the T.INV.2T function to return the inverse of the probability distribution function for a two tailed distribution.
* You can use the T.TEST function to return the probability value from a t distribution.
* This function was added in Excel 2010
* For the Microsoft documentation refer to support.microsoft.com
