Returns the right-tailed Student's t-distribution.
The 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.RT(x,deg_freedom)
The T.DIST.RT 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.
Remarks
- If any argument is nonnumeric, T.DIST.RT returns the #VALUE! error value.
- If deg_freedom < 1, T.DIST.RT returns the #NUM! error value.
