Splet“ANOVA” is used to calculate the “significant” difference between 2 or more “Independent groups”. It is used to determine if the means of the groups differ significantly or not. If the “null hypothesis” is rejected, that is its mean differs significantly, we use a post-hoc test to detect which group is causing the difference or ...
