Answer:
The factorial notation would be 2x3 (i.e., this would be a 2x3 factorial design).
Step-by-step explanation:
A factorial design is one involving two or more factors in a single experiment. Such designs are classified by the number of levels of each factor and the number of factors. So a 2x3 factorial will have three factors each at two levels.
2x3 factorial design has 2 factors & 6 conditions.
