Explanation:
Detailed explanation-1: -When to use a one-way ANOVA. Use a one-way ANOVA when you have collected data about one categorical independent variable and one quantitative dependent variable. The independent variable should have at least three levels (i.e. at least three different groups or categories).
Detailed explanation-2: -If we have two samples, then we go for T-test. But if we have more than two groups then we use ANOVA for comparing their means. So, since ANOVA is used if we have more than two groups and statement “It can only be used with two groups” is absolute contrary to this.
