Varianseanalyse
Varianseanalyse, often abbreviated as ANOVA, is a statistical method used to compare the means of two or more groups. Developed by Ronald Fisher, it partitions the total variation in a dataset into different sources of variation. The primary purpose of ANOVA is to determine whether there are statistically significant differences between the group means. It achieves this by comparing the variance between the groups to the variance within each group.
The fundamental principle behind ANOVA is to test a null hypothesis, which states that all group means
ANOVA can be classified into different types, such as one-way ANOVA, which involves one independent variable
