Answer to Question 1

There are three specific uses of factorial designs that are discussed in the text. (1) A new study can be built by adding a new factor to an earlier research study. (2) A participant characteristic such as age or gender can be used as a second factor to separate participants into more homogeneous groups and reduce variability in a between-subjects design. (3) The order of treatments can be used as a second factor in a counterbalanced within-subjects design to measure the order effects.

Answer to Question 2

probabilistic equivalence
