Within-Subjects Design
1. Understand how correlated-group designs assure initial group equivalence
2. Be able to define correlated-groups designs, matched-subjects designs, and within-subjects designs
3. Understand the problem of confounding in correlated-groups designs
4. Know what sequence effects are and how they are controlled
5. Understand why a repeated-measures ANOVA is used to analyze within-subjects andmatched-subjects designs
6. Understand the strengths and weaknesses of using within-subjects designs
7. Understand practice and carry-over effects and how they are controlled
8. Understand why within-subjects designs should not be used if strong carryover effects areexpected
9. Be able to define randomizing within blocks and understand how it can control sequence effects
Matched-Subjects Design
10. Know the characteristics of matched-subjects designs and when to use them
11. Know how to match participants and how to decide what variables to match on
12. Understand the strengths and weaknesses of matched-subjects designs
Single-Subject Experimental Designs
13. Understand how single-subject designs are extensions of within-subject designs
14. Know when to use single-subject designs and how they protect internal validity
15. Know how single-subject designs differ from case studies
16. Understand the basis for making causal inferences in single-subject experimental designs
