If ANOVA is used to analyze a situation involving two or more independent variables then the analysis is sometimes termed as Factorial ANOVA. However, there are three types of factorial design:
- Independent Factorial Design
- Repeated – measures or Related Factorial Design
- Mixed Design
Independent Factorial Design:
In this type of experiment there are two or more independent variables or predictors and each has been measured between groups.
Repeated – measures or Related Factorial Design:
In this type of experiment, the independent variables (predictors) have been measured however; the same participants remain in all the conditions.
In this kind of experimental design the predictors have been measured with different participants being used for the measurement of some while same participants being used to measure the others.
