# T.INV

### 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`.

Notes
•  `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.

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

`T.INV.2T`: Calculates the inverse of the two-tailed TDIST function.

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

### Step 3. Fill in the 2 values- In this example I have chosen 2 values that are the same.
