Answer to Question 1

The two types of correlated-groups designs are a within-subjects design and a matched-subjects design. Each is considered a correlated-groups design because there is some relationship between the subjects in each group when using these designs. In the within-subjects design, the same people are used in each condition and in the matched-subjects design, subjects are matched on relevant variables before being placed into each condition.
