   In R, you can use the aov() function to run the One-Way ANOVA. The syntax is as follows: model <- aov(dependent_variable ~ group_variable, data = your_data) For example, let’s say we want to test if there is any significant difference in the mean weight of scores across three different classes: model <- aov(score ~ class, data = exam_scores)

   A simple and perhaps perferred 1 way to do an ANOVA in R is to use the aov() function. Let’s try that function on the same model we examined above with the lm() function. aov.model <- aov (size ~ pop) summary (aov.model)

   8 sie 2022 · We use aov() when we would like to fit an ANOVA model and view the results in an ANOVA summary table. We use anova() when we would like to compare the fit of nested regression models to determine if a regression model with a certain set of coefficients offers a significantly better fit than a model with only a subset of the coefficients.
