Excel - FINV Function



FINV Function

The Excel FINV function is based on the F distribution to ascertain the critical values. It will retrieve the inverse of the (right-tailed) F probability distribution. It is generally used in the Regression model, ANOVA, and another statistical model to verify whether there are significant differences in calculated variances of two data sets. For instance, you can figure out if two groups have the same diversity of medical kits by looking at their F distribution.

If t = FDIST(z...), then FINV (t...) = z

The FINV function replaces the F.INV.RT function in Excel 2010.

Compatibility

This advanced Excel function is compatible with the following versions of MS-Excel −

  • Excel for Microsoft 365
  • Excel for Microsoft 365 for Mac
  • Excel for the web
  • Excel 2021
  • Excel 2021 for Mac
  • Excel 2019
  • Excel 2019 for Mac
  • Excel 2016

Syntax

The syntax of FINV function is as follows −

FINV (probability,deg_freedom1,deg_freedom2)

Arguments

You can use the following arguments with the FINV function −

Argument Description Required / Optional
Probability A probability associated with the F cumulative distribution. Required
Deg_freedom1 The numerator degrees of freedom. Required
Deg_freedom2 The denominator degrees of freedom. Required

Points to Remember

  • FINV function retrieves the #VALUE! error if its arguments contain non-numeric values.
  • If probability doesnt lie between 0 and 1, then FINV retrieves the #NUM! Error.
  • If deg_freedom1 or deg_freedom2 contains a decimal value, it is truncated.
  • Either the deg_freedom1 < 1 or deg_freedom1 ≥ 1010, the FINV function will retrieve the #NUM! Error.
  • If the deg_freedom2 < 1 and deg_freedom2 ≥ 1010, the FINV function will receive the #NUM! Error.
  • The FINVs precision relies on FDISTs precision. This function generally employed an iterative search technique. The FINV retrieves the #N/A error if the search is unsuccessful after a hundred iterations.

Examples of FINV Function

Practice the following examples to learn the use of the FINV function in Excel.

Example 1

Consider the sample worksheet, which has two columns, B and C. In the C7 cell, enter the formula =FINV(C4,C5,C6) and press the Enter tab.

Excel FINV Function 1

Excel FINV Function 2

Example 2

FINV function retrieves the #VALUE! Error if its arguments contain non-numeric values.

Solution

You may enter the FINV formula =FINV("Henry," 14,13) in the C9 cell where the first argument indicates the text string and the remaining arguments are numeric.

Excel FINV Function 3

Once you press the Enter tab, the #VALUE! error will be obtained.

Excel FINV Function 4

Example 3

If probability doesnt lie between 0 and 1, then FINV retrieves the #NUM! Error.

Solution

You may write the formula =FINV(20,18,13) in the C9 cell and press the Enter tab. Here, the first argument, probability, is 20, greater than 1.

Excel FINV Function 5

Therefore, the incorrect result #NUM! Error is generated. You can modify the first argument to get the accurate result of the FINV function.

Excel FINV Function 6

Example 4

If deg_freedom1 or deg_freedom2 contains a decimal value, it is truncated.

Solution

Enter the formula =FINV(C4,C5,C6) in the C7 cell as the value of deg_freedom1 is 10.4 which will be truncated to become the integer 10.

Excel FINV Function 7

Now, press the Enter key to get the result.

Excel FINV Function 8

Example 5

Either the deg_freedom1 < 1 or deg_freedom1 ≥ 1010, the FINV function will retrieve the #NUM! Error.

Solution

You may write the formula =FINV(20,10^12,13) in the C9 cell. The second argument is 10^12, larger than the 10^10.

Excel FINV Function 9

Once you press the Enter tab, the output is #NUM! error. You may alter the second argument, whose values must lie between 0 and 10^10 to obtain the correct result.

Excel FINV Function 10

Example 6

If the deg_freedom2 < 1 and deg_freedom2 ≥ 1010, the FINV function will receive the #NUM! Error.

Solution

First, enter the formula =FINV(20,19,-15) in the C9 cell and press the Enter tab. The third argument, degree of freedom2, is negative, which is not permissible.

Excel FINV Function 11

Therefore, the resulting value is #NUM! error. You may alter the third argument to get an accurate result.

Excel FINV Function 12

Conclusion

To successfully execute the FINV function, you need to employ all the crucial points mentioned in this chapter. If you specify the wrong cell references or non-numeric values in the arguments, errors will arise.
