Apr 9, 2016 at 1:17 | comment | added | Silverfish | It's important to distinguish between the number of levels that a particular categorical variable (sometimes called a "factor") can have, versus the number of variables. I think this is something that causes learners confusion. For instance, if I measure some response (i.e. dependent) variable for subjects under three different conditions (e.g. Drug A, Drug B, Drug C) then I have only one independent variable (the drug used), which happens to have three levels. That's only a one-way ANOVA and not (as some students think) a three-way. | |

Apr 9, 2016 at 1:10 | comment | added | Silverfish | Welcome to our site! See, for instance, in Wikipedia: "two-way analysis of variance (ANOVA) is an extension of the one-way ANOVA that examines the influence of two different categorical independent variables on one continuous dependent variable." Three-way or four-way is analogous. (One-way ANOVA has only one independent categorical variable, of course.) | |
