| | | If any argument is not numeric, then #VALUE! is returned. |
| | | If "probability" < 0, then #NUM! is returned. |
| | | If "probability" > 1, then #NUM! is returned. |
| | | If "degrees_freedom1" is not an integer, it is truncated. |
| | | If "degrees_freedom1" < 1, then #NUM! is returned. |
| | | If "degrees_freedom1" = 10^10, then #NUM! is returned. |
| | | If "degrees_freedom2" is not an integer, it is truncated. |
| | | If "degrees_freedom2" < 1, then #NUM! is returned. |
| | | If "degrees_freedom2" = 10^10, then #NUM! is returned. |
| | | FINV can be used to return critical values from the F distribution. For example, the output of an ANOVA calculation often includes data for the F statistic, F probability, and F critical value at the 0.05 significance level. To return the critical value of F, use the significance level as the probability argument to FINV. |
| | | FINV uses an iterative technique for calculating the function. Given a probability value, FINV iterates until the result is accurate to within ± 3x10^-7. If FINV does not converge after 100 iterations, the function returns the #N/A error value. |
| | | The F distribution can be used in an F-test that compares the degree of variability in two data sets. For example, you can analyze income distributions in the United States and Canada to determine whether the two countries have a similar degree of diversity. |
| | | The accuracy of this function was improved in Excel 2003. For more information please refer to this Knowledge Base Article (828332). |
