Information
has glosseng: 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 fit to a data set, in order to identify the model that best fits the population from which the data were sampled. Exact F-tests mainly arise when the models have been fit to the data using least squares. The name was coined by George W. Snedecor, in honour of Sir Ronald A. Fisher. Fisher initially developed the statistic as the variance ratio in the 1920s.

Meaning
German
has glossdeu: Als F-Test wird allgemein eine Gruppe von Tests bezeichnet bei denen die Teststatistik unter der Nullhypothese einer F-Verteilung folgt. Häufig ist mit F-Test ein statistischer Test gemeint, mithilfe dessen mit einer gewissen Konfidenz entschieden werden kann, ob zwei Stichproben aus unterschiedlichen, normalverteilten Populationen sich hinsichtlich ihrer Varianz wesentlich unterscheiden. Er dient damit unter anderem zur generellen Überprüfung von Unterschieden zwischen zwei statistischen Populationen.

has glossjpn: F検定(エフけんてい)とは、帰無仮説が正しければ統計量がF分布に従うような統計学的検定の総称である。次のようなものがある: # 正規分布に従う2つの群の「標準偏差が等しい」という帰無仮説の検定。これはt検定の前段階の「等分散性検定」として用いられる。 # 正規分布に従う複数の群(標準偏差は等しいと仮定する)で、「平均が等しい」(つまり同じ母集団に由来する)という帰無仮説の検定。この方法は分散分析に用いられる。

has glossnld: De F-toets is een statistische toets om na te gaan of van twee normale verdelingen de varianties verschillen. De F-toets wordt gebruikt bij variantie-analyse en is een parametrische toets omdat de verdeling normaal moet zijn.

has glosstur: F-testi istatistik bilimi içinde bir sıra değişik problemlerde kullanılan parameterik çıkarımsal sınama yöntemidir. F-testi sıfır hipotezine göre gerçekte bir F-dağılımı gösteren sınama istatistiği bulunduğu kabul edilen hallerde, herhangi bir istatistiksel sınama yapma şeklidir. Bu çeşit bir istatistiksel sınama önce Ronald Fisher tarafından 1920li yıllarda tek yönlü varyans analizi için ortaya atılıp kullanılmış ve sonradan diğer şekillerde F-dağılım kullanan sınamalar da ortaya atılınca, bu çeşit sınamalara genel isim olarak F-testi adı verilmesi Ronald Fisher anısına George W. Snecedor tarafından teklif edilip, istatistikçiler tarafından F-testi bir genel isim olarak kabul edilmistir.
