    While this guide provides a comprehensive overview of ANOVA, there's always more to explore. To dive deeper into the world of ANOVA, consider:

    The type of ANOVA to use depends on the research question and the design of the experiment. For example, one-way ANOVA is used for a single independent variable, while two-way ANOVA is used for two independent variables.

    ANOVA assumes that the data is normally distributed, the variance is equal across all groups, and the observations are independent.
