The T.DIST.2T function returns the two tailed Student distribution for a value x. Along with T.DIST.RT, this function replaces TDIST and is equivalent to calling TDIST with the tails argument set to 2.
Parts of a T.DIST.2T function
T.DIST.2T(x, degrees_freedom)
| Part | Description |
x |
Required. The x value to evaluate the distribution at. |
degrees_freedom |
Required. The degrees of freedom. |
Sample formulas
Example 1: T.DIST.2T(1.96, 60)
Example 2: T.DIST.2T(1, 2)
Notes
- If deg_freedom is less than 1, returns an #NUM error.
- If x is negative, returns an #NUM error.
- Along with
T.DIST.RT, this formula replaces theTDISTformula. This is equivalent to calling theTDISTformula with tails = 2.
