# How to Use T.DIST.2T function in Google Sheets in 2020?

T.DIST.2T functionThe 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 the TDIST formula. This is equivalent to calling the TDIST formula with tails = 2.
