Returns the t-value of the Student's t-distribution as a function of the probability and the degrees of freedom.

Syntax

TINV ( probability , degrees_freedom )

Probability is the probability associated with the two-tailed Student's t-distribution.

Degrees_freedom is the number of degrees of freedom to characterize the distribution.

Remarks

  • If either argument is nonnumeric, TINV returns the #VALUE! error value.

  • If probability < 0 or if probability > 1, TINV returns the #NUM! error value.

  • If degrees_freedom is not an integer, it is truncated.

  • If degrees_freedom < 1, TINV returns the #NUM! error value.

  • TINV is calculated as TINV = p( t<X ), where X is a random variable that follows the t-distribution.

  • 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 TINV(0.05,10), which returns 2.28139. The one-tailed value for the same probability and degrees of freedom can be calculated with TINV(2*0.05,10), which returns 1.812462.

    Note: In some tables, probability is described as (1-p).

TINV uses an iterative technique for calculating the function. Given a probability value, TINV iterates until the result is accurate to within 3x10^-7. If TINV does not converge after 100 iterations, the function returns the #N/A error value.
