Varianzzerlegung
Varianzzerlegung, also known as analysis of variance (ANOVA) in English, is a statistical method used to partition the observed total variance in a dataset into different components that can be attributed to various sources of variation. This technique is particularly useful for comparing the means of three or more groups. The core idea is to analyze the differences between group means in relation to the variability within each group.
The total variance in the data is decomposed into variance between groups and variance within groups. The
A key output of varianzzerlegung is the F-statistic, which is the ratio of the variance between groups
