Calculates the left-tailed Student’s t-distribution evaluated at the given number.

Sample Usage

TDIST(1,30,TRUE)
TDIST(1,30,FALSE)

Syntax

TDIST(number, degrees_freedom, cumulative)

  • number - The value at which to evaluate the t-distribution function.
  • degrees_freedom - An integer indicating the degrees of freedom for the t-distribution.
  • cumulative - A logical value that determines the form of the function. 

 

Examples

TDIST(1,30,TRUE) returns a value of 0.8373
TDIST(1,30,FALSE) returns a value of 0.2379

Notes

  • number and degrees_freedom must be numeric.
  • Set cumulative to TRUE to use the cumulative distribution function, and set it to FALSE to use the probability density function.
