| | | 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. |
| | | If any of the arguments are not numeric, then #VALUE! is returned. |
| | | If "degrees_freedom" is not an integer, it is truncated. |
| | | If "degrees_freedom" < 1, then #NUM! is returned. |
| | | If "tails" is not an integer, it is truncated. |
| | | If "tails" = 1, then the one-tailed distribution is used. |
| | | If "tails" = 2, then the two-tailed distribution is used. |
| | | If "tails" is any value other than 1 or 2, then #NUM! is returned. |
| | | Example 1 - This is the probability of a value equal to or greater than 1.96 with 10 degrees of freedom. |
