An F-test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. It is most often used when comparing statistical models that have been fitted to a data set, in order to identify the model that best fits the population from which the data were sampled. Exact "F-tests" … See more Common examples of the use of F-tests include the study of the following cases: • The hypothesis that the means of a given set of normally distributed populations, all having the same standard deviation, are equal. This is … See more • Fox, Karl A. (1980). Intermediate Economic Statistics (Second ed.). New York: John Wiley & Sons. pp. 290–310. ISBN 0-88275-521-8. • Johnston, John (1972). Econometric Methods (Second ed.). New York: McGraw-Hill. pp. 35–38. See more Most F-tests arise by considering a decomposition of the variability in a collection of data in terms of sums of squares.
