Usage

Use the F.INV formula with the syntax shown below, it has 3 required parameters:

=F.INV(probability, degrees_freedom1, degrees_freedom2)

1. probability (required):
   The probability at which to evaluate the distribution. Must be between 0 and 1.
2. degrees_freedom1 (required):
   The number of degrees of freedom in the numerator of the F distribution. Must be a positive integer.
3. degrees_freedom2 (required):
   The number of degrees of freedom in the denominator of the F distribution. Must be a positive integer.

Examples

Find critical F-value for ANOVA test

When performing an analysis of variance (ANOVA) test, the F-value is used to determine if there is a significant difference between group means. By using F.INV with a probability of 0.05 and the appropriate degrees of freedom, you can find the critical F-value for the test.

Calculate confidence interval for regression slope

When performing a linear regression, the F-value is used to calculate the confidence interval for the slope of the regression line. By using F.INV with a probability of 0.05 and the appropriate degrees of freedom, you can find the critical F-value to use in the calculation.

Calculate p-value for F-test

When comparing the variances of two samples using an F-test, the p-value is used to determine if the difference between the variances is significant. By using F.INV with the appropriate degrees of freedom and the observed F-value, you can calculate the p-value for the test.

Common Mistakes

Incorrect probability value

The probability value should be between 0 and 1. Double check that the value entered is within this range.

Invalid degrees of freedom

The degrees of freedom should be positive integers. Ensure that the values entered are valid and within the allowable range.

Incorrect order of degrees of freedom

Ensure that the degrees of freedom are entered in the correct order. degrees_freedom1 should be the numerator degrees of freedom and degrees_freedom2 should be the denominator degrees of freedom.

Related Formulas

The following functions are similar to F.INV or are often used with it in a formula:

• F.DIST

  The F.DIST function calculates the cumulative distribution function (CDF) of the F-distribution. This function is commonly used in statistical analysis to determine the probability that two variances are from the same population. The result of F.DIST is the probability that the random variable of an F-distribution is less than or equal to a specified value.

• T.INV

  The T.INV function returns the inverse of the Student's t-distribution for the provided probability and degrees of freedom. This function is commonly used to calculate a critical value from the t-distribution when working with small sample sizes.

• NORM.INV

  The NORM.INV function returns the inverse of the cumulative normal distribution for a specified mean and standard deviation. It is commonly used in statistical analysis to find the value at which a specified percentage of observations occur below that value.
