This calculator will tell you the critical value of the F-distribution, given the probability level, the numerator degrees of freedom, and the denominator degrees of freedom.

This calculator will compute the cumulative distribution function (CDF) for the Fisher F-distribution (i.e., the area under the F-distribution from 0 to x), given the numerator and denominator degrees of freedom, and the upper limit of integration x.

This calculator will compute the cumulative distribution function (CDF) for the noncentral F-distribution, given an F-value, the numerator and denominator degrees of freedom, and the noncentrality parameter.

This calculator will tell you the expected value (i.e., the mean) for an F-distribution random variable, given the denominator degrees of freedom.

This calculator will tell you the Fisher F-value for a multiple regression study and its associated probability level (p-value), given the model R^{2}, the number of predictors in the model, and the total sample size.

This calculator will compute the F-value associated with an analysis of variance (ANOVA) study, given the between-groups (treatment) mean square and the within-groups (error) mean square.

This calculator will tell you the F-value for a hierarchical multiple regression study, given an R^{2} value for a set of independent variables A, an R^{2} value for the sum of A and another set of independent variables B, the number of predictors in A, the number of predictors in B, and the total sample size. The value returned by the calculator is the the F-value associated with the addition of B to the model.

This calculator will tell you the probability value of an F-test, given the F-value, numerator degrees of freedom, and denominator degrees of freedom.

This calculator will compute the probability density function (PDF) for the Fisher F-distribution, given the numerator and denominator degrees of freedom, and the point at which to evaluate the function x.

This calculator will tell you the variance for an F-distribution random variable, given the numerator and denominator degrees of freedom.
