Returns the Student's left-tailed 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.

Sample Usage

Syntax

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.

Remarks

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.
