# How to use T.DIST.2T Function in Excel

Returns the two-tailed Student’s t-distribution. The Student’s t-distribution is used in the hypothesis testing of small sample data sets. Use this function in place of a table of critical values for the t-distribution.

Syntax:= T.DIST.2T(x,deg_freedom)

The T.DIST.2T function syntax has the following arguments:

• X     Required. The numeric value at which to evaluate the distribution.
• Deg_freedom     Required. An integer indicating the number of degrees of freedom.

Example: Let’s look at some Excel T.DIST.2T function examples and explore how to use the T.DIST.2T function as a worksheet function in Microsoft Excel:

Syntax:  =T.DIST.2T(B1,B2)

Result: 0.295167235

Note:

• If any argument is nonnumeric, T.DIST.2T returns the #VALUE! error value.
• If deg_freedom < 1, T.DIST.2T returns the #NUM! error value.
• If x < 0, then T.DIST.2T returns the #NUM! error value.
