T.INV.2T Function Explained

The T.INV.2T Function in Microsoft Excel returns the two-tailed probability of the Student’s t-Distribution, given a probability and the degrees of freedom. It has two arguments: probability and deg_freedom. The probability argument is the probability associated with the two-tailed Student’s t-Distribution, and the deg_freedom argument is the number of degrees of freedom.

T.INV.2T Function Syntax

T.INV.2T(probability, degrees_freedom)

  • probability: The probability associated with the two-tailed Student’s t-distribution. Must be a number between 0 and 1.
  • degrees_freedom: The number of degrees of freedom with which to characterize the distribution. Must be a positive number.
