What the one-way ANOVA for?
... A one-way ANOVA is used to understand whether exam performance differed based on the anxiety levels amongst students, dividing students into three independent groups (e.g., low, medium and high-stressed students). It only tells you that at least two groups were different. Since you may have three, f ...
