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.

WebCommençons par calculer notre statistique de test. Pour ce faire, il faut d'abord trouver la différence entre les deux moyennes : 22,29 − 14, 95 = 7, 34 22, 29 − 14, 95 = 7, 34. Cette différence dans nos échantillons est une estimation de la différence entre les moyennes de population des deux groupes. Ensuite, calculons l'écart-type ... WebThe least significant difference (LSD) test is used in the context of the analysis of variance, when the F -ratio suggests rejection of the null hypothesis H 0, that is, when the difference between the population means is significant. This test helps to identify the populations whose means are statistically different.
