T.INV.2TThe T.INV.2T function calculates the inverse of the two-tailed TDIST function.
probability – The probability associated with the two-tailed 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.2T is to be used for the inverse of two-tailed TDIST functions.
T.INV.2T is synonymous with TINV.
To calculate the negative inverse of the one-tailed TDIST function, use T.INV.
Both arguments to T.INV.2T must be numeric or a destination cell whose value is numeric.
TDIST: Calculates the probability for Student’s t-distribution with a given input (x).
T.INV: Calculates the negative inverse of the one-tailed TDIST function.
In this example, T.INV.2T uses the probability associated with a Student’s two-tailed t-distribution and degrees of freedom to return its result.
