Analysis of variance - Wikipedia
Most F-tests arise by considering a decomposition of the variability in a collection of data in terms of sums of squares. The test statistic in an F-test is the ratio of two scaled sums of squares reflecting different sources of variability. These sums of squares are constructed so that the statistic tends to be greater when the null hypothesis is not true. In order for the statistic to follow the F-distribution under the null hypothesis, the sums of squares should be statistically independent, … WebOne-way ANOVA (analysis of variance) was proposed by Ronald Fisher. 679 ANOVA proposes the null hypothesis that all the means of compared groups are equal. ANOVA assumes that the underlying analysis data are normally distributed. ... Analysis of variance (ANOVA) is the statistical procedure of comparing the means of a variable across several ...
