explain please. ANOVA: Analysis of Variance - Similar to the t-test in which we compared two group means, ANOVA allows us to similarly test means of more than 2 groups. It is also referred to as the F-test. If ANOVA was used with 2 categories Nominal, the t-test and F-test would be the same finding. But it's not limited to just 2 categories as the t-test is. Interval/Ratio, Ordinal (w/4 or more categories exception) Dependent variable and a Nominal or Ordinal (3+ cat.) Independent variable is often used
