One-way ANOVA (Analysis of Variance) is used when you have one independent variable (factor) and one dependent variable. It allows you to compare means across multiple groups to determine if they are statistically different from one another. This can be thought of as comparing the means of different treatments or conditions.
Two-way ANOVA, on the other hand, is used when you have two independent variables (factors) and one dependent variable. It allows you to determine the main effects of each factor as well as any interactions between them. The main effects show the individual effect of each factor on the dependent variable, while the interaction effect shows how the combination of factors affects the dependent variable.
In summary, the main difference between one-way ANOVA and two-way ANOVA is the number of independent variables being analyzed. One-way ANOVA is used when there is only one independent variable, while two-way ANOVA is used when there are two independent variables.
