# How to Use F.INV.RT in Google Sheets in 2020?

F.INV.RTThe 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 than 1.

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 and degrees_freedom2 are truncated to an integer in the calculation if a non-integer is provided as an argument.

Both degrees_freedom1 and degrees_freedom2 must be at least 1.

All arguments must be numeric.

F.INV.RT is synonymous with FINV.

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.
