ANOVA, 1 and 2 way

ANOVA, or Analysis of Variance, is a statistical method used to analyze the differences among group means in a sample.

There are two main types of ANOVA: one-way ANOVA and two-way ANOVA.

One-Way ANOVA is used when there is one independent variable (factor) with more than two levels (groups).

Two-Way ANOVA is an extension of One-Way ANOVA and is used when there are two independent variables (factors).
