Analysis of Variance, or ANOVA, is a statistical tool used to evaluate mean differences between different groups in a sample. An analysis of variance (ANOVA) is very useful in determining statistically significant differences between three or more groups/conditions. Through the assessment of whether the difference between group means exceeds the variation within groups, ANOVA is useful in a variety of research and experimental contexts.
One-way ANOVA is the suitable option when dealing with a single categorical independent variable that has more than two levels and requires a comparison of their means.The principles of one-way ANOVA are expanded upon by Two-Way ANOVA for a more comprehensive investigation incorporating two independent variables and an analysis of their interaction.Multifactor ANOVA is used in situations where there are more than two independent variables or components that may interact intricately.
