3 Way Repeated Measures Anova. Divide the 3-way analysis into 2-way analyses. Aovrepeated. Be sure you understand what questions three-way ANOVA can answer they might not actually be the questions you care about. Three way repeated measures ANOVA.
Three way repeated measure ANOVA is sufficient for your expt. As such it extends the two-way ANOVA which is used to determine if such an interaction exists between just two independent variables ie rather than three independent variables. Three-Factors Repeated Measures ANOVA This model is suitable for complex single-group fMRI designs. Here is my example. For example you may conduct a 2-way analysis AB at each level of C. Currently three-way ANOVA in Prism 8 is restricted to a 2 x 2 x K design.
The main goal of two-way and three-way repeated measures ANOVA is respectively to evaluate if there is a statistically significant interaction effect between two and three within-subjects factors in explaining a continuous outcome variable.
When reporting the results of a repeated measures ANOVA we always use the following general structure. Aovrepeated. Three way repeated measures ANOVA. Three way repeated measure ANOVA is sufficient for your expt. Say for example that a bc interaction differs across various levels of factor a. I can run these for the 2-way interactions using the method RepeatedMeasuresModelmultcompare but I cannot figure out how to do it for the 3-way interaction.
