T.DIST Function Explained

The T.DIST Function in Microsoft Excel calculates the left-tailed probability of the Student’s t-distribution. It takes two arguments: the x value and the deg_freedom. The x value is the numeric value at which to evaluate the function and the deg_freedom is the number of degrees of freedom. The result is the probability associated with the t-distribution.

T.DIST Function Syntax

T.DIST(x,deg_freedom,cumulative)

  • x: The value for which you want to calculate the distribution.
  • deg_freedom: The number of degrees of freedom, a number equal to the number of values in each sample minus 1.
  • cumulative: 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.
