a mixed-design analysis of variance model (also known as a split-plot ANOVA) is used to test for differences between two or more independent groups whilst subjecting participants to repeated measures. Thus, in a mixed-design ANOVA model, one factor (a fixed effects factor) is a between-subjects variable and the other (a random effects factor) is a within-subjects variable. Thus, overall, the model is a type of mixed effect model.
- What relation is between mixed design and split-plot design? Is a split-plot design a within-subject design, or a between-subject design, or both?
- Why is the model of a mixed design a mixed effect model? Which input variable has random effect and which input variable has fixed effect?
