## Definition

Calculates the inverse of the two-tailed TDIST function.

### Sample Usage

`T.INV.2T(0.35, 1)`

`T.INV.2T(A1, A2)`

### Syntax

`T.INV.2T(probability, degrees_freedom)`

### Notes

`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.

### See Also

`TDIST`

: Calculates the probability for Student's t-distribution with a given input (x).

`TINV`

: Calculates the inverse of the two-tailed TDIST function.

: Calculates the negative inverse of the one-tailed TDIST function.

### Examples

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.
