Student t distribution formula in advanced excel
Find the percentage points (probability) for the
Student t distribution where a numerical value (x) is a calculated value of t for which the percentage points are to be calculated. The t-distribution is used in the hypothesis test of small sample data sets. Use this function in place of a table of critical values for the t distribution. The DIST function calculates the Student's T distribution, which is a continuous probability distribution often used to test hypotheses against small sample data sets. Returns the probability of percentage points for the t distribution.Syntax of Student t distribution formula
TDIST(x,
degrees_freedom, tails)
Challenges to use Student t distribution formula
If "x" is 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 "degrees_freedom" is not numeric, then #VALUE! 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.
If "tails" is not numeric, then #VALUE! is returned.
