The F.INV.RT function calculates the inverse of the right-tailed F probability distribution. Also called the Fisher-Snedecor distribution or Snedecor’s F distribution.
Sample Usage
F.INV.RT(0.42, 2, 3)
F.INV.RT(A2, B2, C2)
Syntax
F.INV.RT(probability, degrees_freedom1, degrees_freedom2)
-
probability
- The probability associated with the right-tailed F-distribution.- Must be greater than
0
and less than1
.
- Must be greater than
-
degrees_freedom1
- The number of degrees of freedom of the numerator of the test statistic. -
degrees_freedom2
- The number of degrees of freedom of the denominator of the test statistic.
Notes
- Both
degrees_freedom1
anddegrees_freedom2
are truncated to an integer in the calculation if a non-integer is provided as an argument. - Both
degrees_freedom1
anddegrees_freedom2
must be at least1
. - All arguments must be numeric.

CHIINV: Calculates the inverse of the right-tailed chi-squared distribution.
F.DIST: Calculates the right-tailed F probability distribution (degree of diversity) for two data sets with given input x. Alternately called Fisher-Snedecor distribution or Snedecor’s F distribution.
F.INV: Calculates the inverse of the left-tailed F probability distribution. Also called the Fisher-Snedecor distribution or Snedecor’s F distribution.
FTEST: Returns the probability associated with an F-test for equality of variances. Determines whether two samples are likely to have come from populations with the same variance.
TINV: Calculates the inverse of the two-tailed TDIST function.
Example
Suppose you want to find the cutoff for the F statistic associated with a p-value of 0.05
. With 4
and 5
as the degrees of freedom, you can consider any F statistic larger than 5.19
to be statistically significant.
