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.
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.
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.
The example may be easier to understand if you copy it to a blank worksheet.
