Syntax of T.INV function

T.INV(probability,deg_freedom)

The T.INV function syntax has the following arguments:

• Probability: The probability associated with the Student’s t-distribution.
• Deg_freedom:  The number of degrees of freedom with which to characterize the distribution.

Explanation T.INV function

• If either argument is nonnumeric, T.INV returns the #VALUE! error value.
• If probability <= 0 or if probability > 1, T.INV returns the #NUM! error value.
• If deg_freedom is not an integer, it is truncated.
• If deg_freedom < 1, T.INV returns the #NUM! error value.
