Definition of T.INV:

This formula calculates the negative inverse of the one-tailed TDIST function.

Sample Usage

T.INV(0.35, 1)

T.INV(A1, A2)


Syntax for T.INV: 

  • T.INV(probability, degrees_freedom)
    • probability - The probability associated with the t-distribution.

      • Must be greater than 0 and less than 1.

  • degrees_freedom - The number of degrees of freedom.

  • Truncated to an integer in the calculation if a non-integer is provided as an argument.

  • Must be greater than or equal to 1.

  •  T.INV is to be used for the negative inverse of the one-tailed TDIST function.
  • Both arguments to T.INV must be numeric or a destination cell whose value is numeric.
