= F Test = An '''F test''' is a statistical test for whether a random variable follows the [[Analysis/FDistribution|F distribution]]. <> ---- == Description == The [[Analysis/FDistribution|F distribution]] is a ratio of normalized [[Analysis/ChiSquaredDistribution|chi-squared distributed]] random variables. Correspondingly, there is a connection between F statistics and [[Statistics/PearsonsChiSquaredTest|chi-squared statistics]]: as the denominator degrees of freedom get larger, the relationship converges to ''chi-squared = (numerator degrees of freedom) * F''. ---- == Usage == ---- CategoryRicottone
