F.INV function - The function returns the inverse of the probability distribution F in Excel

The following article introduces you to F.INV - one of the functions in the group of statistical functions that is very popular in Excel.

Description: The function returns the inverse of the probability distribution F. The support function is from Excel 2010 version.

Syntax: F.INV (probability, deg_freedom1, deg_freedom2)

Inside:

- probability: Probability associated with the cumulative distribution F, is a required parameter.

- deg_freedom1: The degree of freedom in the numerator, is a required parameter.

- deg_freedom2: The degrees of freedom in the denominator, are required parameters.

Attention:

- If any parameters are not numeric -> the function returns the #VALUE! Error value .

- If probability <0 or probability> 1 -> the function returns the #NUM! Error value

- If deg_freedom1 , deg_freedom2 are not whole numbers -> they are truncated to integers.

- If deg_freedom1 <1 or deg_freedom2 <1 -> the function returns the #NUM! Error value

For example:

Calculate the inverse value of probability distribution F according to the data in the following data table:

- In the cell to calculate enter the formula : = F.INV (D6, D7, D8)

- Press Enter -> the inverse value of probability distribution F is:

- Where the probability associated with the cumulative distribution F ≥ 1 -> the function returns the #NUM! Error value

- If the number of degrees of freedom in the numerator and sample is less than 1 -> the function returns the #NUM! Error value

Above are instructions and some specific examples when using F.INV function in Excel.

Good luck!
