T.INV.2T function: Description, Usage, Syntax, Examples and Explanation

by

What is T.INV.2T function in Excel?

T.INV.2T function is one of Statistical functions in Microsoft Excel that returns the two-tailed inverse of the Student’s t-distribution.

Syntax of T.INV.2T function

T.INV.2T(probability,deg_freedom)

The T.INV.2T 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 of T.INV.2T function

  • If either argument is nonnumeric, T.INV.2T returns the #VALUE! error value.
  • If probability <= 0 or if probability > 1, T.INV.2T returns the #NUM! error value.
  • If deg_freedom is not an integer, it is truncated.
  • If deg_freedom < 1, T.INV.2T returns the #NUM! error value.
  • T.INV.2T returns that value t, such that P(|X| > t) = probability where X is a random variable that follows the t-distribution and P(|X| > t) = P(X < -t or X > t).
  • A one-tailed t-value can be returned by replacing probability with 2*probability. For a probability of 0.05 and degrees of freedom of 10, the two-tailed value is calculated with T.INV.2T(0.05,10), which returns 2.28139. The one-tailed value for the same probability and degrees of freedom can be calculated with T.INV.2T(2*0.05,10), which returns 1.812462.Given a value for probability, T.INV.2T seeks that value x such that T.DIST.2T(x, deg_freedom, 2) = probability. Thus, precision of T.INV.2T depends on precision of T.DIST.2T.

Example of T.INV.2T function
