T.DIST function

Returns the 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.


T.DIST(x,deg_freedom, cumulative)

The T.DIST 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.

  • Cumulative     Required. A logical value that determines the form of the function. If cumulative is TRUE, T.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.


  • If any argument is nonnumeric, T.DIST returns the #VALUE! error value.

  • If deg_freedom < 1, T.DIST returns an error value. Deg_freedom needs to be at least 1.
