Factorial Design Notation Explained
Factorial experimental designs use a notation system to describe the factors (independent variables) and the number of levels (conditions) each factor has.
The notation 'A x B' indicates a design with two factors, where the first factor has 'A' levels and the second factor has 'B' levels.
Interpreting the 3 x 3 Notation
In a '3 x 3' factorial design:
- The number of factors (independent variables) is two.
- The number '3' signifies that each of these two factors has three levels or conditions.
This setup allows researchers to study the main effects of each variable and the interaction effect between them across three different settings for each.
Conclusion
Therefore, a 3 x 3 factorial design represents two independent variables, each with three conditions.
