Learn how to use the F-test to compare variances or fit models to data. Find the formula, examples and applications of the F-test in one-way ANOVA, regression and multiple comparison testing.
The F Value is calculated using the formula F = (SSE 1 – SSE 2 / m) / SSE 2 / n-k, where SSE = residual sum of squares, m = number of restrictions and k = number of independent variables. Find the F Statistic (the critical value for this test). The F statistic formula is: F Statistic = variance of the group means / mean of the within group ...
Learn how to conduct an F test to check the equality of variances of two populations or samples using the F statistic and the F table. Find out the F test formula, critical value, and examples for different types of F tests.
18 sie 2020 · An F-test is used to test whether two population variances are equal. The null and alternative hypotheses for the test are as follows: H0: σ12 = σ22 (the population variances are equal) H1: σ12 ≠ σ22 (the population variances are not equal) The F test statistic is calculated as s12 / s22.
