I think your supposed to do this yourself..
Explanation:
The main reason for using a factorial design instead of separate experiments (with one iv per experiment) is to find an interaction between the independent variables.
Factorial designs allows the effect of a factor to be estimated at several levels of the other factors, giving conclusions that are valid over a range of experimental conditions. It is necessary when interactions are present to avoid misleading conclusions and it is more efficient than the 1-factor.
Interactions are measured as the mean of the differences between simple effects. So, in such experiments we study the individual effects of each factors and their interactions. And in factorial experiments a wide range of factors are used.
