Excel F.DIST Function

doc dec2oct 1


The Excel F.DIST function returns the F probability distribution which is usually used to measure the degree of diversity between two data sets.

Syntax and arguments

Formula syntax



  • X: Required, the value of the function. It must be ≥ 0.
  • Deg_freedom1: Required, the numerator degrees of freedom. It must be > 1.
  • Deg_freedom2: Required, the denominator degrees of freedom. It must be > 1.
  • Cumulative: Required, a logical argument that specifies the type of the exponential function to be returned.
      TRUE: returns the cumulative distribution function;
      FALSE: returns the probability density function.


1. The function returns #VALUE! error value if any arguments of F.DIST function is a non-numeric value.

2. The function returns #NUM! error value when:

  • X is negative;
  • Either deg_freedom1 or deg_freedom2 < 1.

3. If deg_freedom1 or deg_freedom2 is not an integer, it will be truncated.


Excel 2010 and later versions

Usage and Examples

Basic usage

For instance, in list C2:C4 contains arguments x, deg_freedom1 and deg_freedom2, to get the relative F probability by using cumulative distribution function or probability density function, please use the formula as these:

=F.DIST(C2,C3,C4,TRUE)   //Return cumulative distribution function

=F.DIST(C2,C3,C4,FALSE)   //Return probability density function

Press Enter key.
