F.DIST function

Returns the F probability distribution. You can use this function to determine whether two data sets have different degrees of diversity. For example, you can examine the test scores of men and women entering high school and determine if the variability in the females is different from that found in the males.

Syntax

F.DIST(x,deg_freedom1,deg_freedom2,cumulative)

The F.DIST function syntax has the following arguments:

  • X     Required. The value at which to evaluate the function.

  • Deg_freedom1     Required. The numerator degrees of freedom.

  • Deg_freedom2     Required. The denominator degrees of freedom.

  • Cumulative      Required. A logical value that determines the form of the function. If cumulative is TRUE, F.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function.

Remarks

  • If any argument is nonnumeric, F.DIST returns the #VALUE! error value.

  • If x is negative, F.DIST returns the #NUM! error value.

  • If deg_freedom1 or deg_freedom2 is not an integer, it is truncated.

  • If deg_freedom1 < 1, F.DIST returns the #NUM! error value.

  • If deg_freedom2 < 1, F.DIST returns the #NUM! error value.
