Can have 1 to 30 arguments. Arguments should be either numbers, or arrays or references that contain numbers. 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. X is the numeric value at which to evaluate the distribution.
Tails specifies the number of distribution tails to return.
Probability is the probability associated with the Student's t-distribution. Returns the probability associated with a Student's t-Test. Array1 is an array or range containing the first data set. Array2 is an array or range containing the second data set. Tails specifies the number of distribution tails.
