Chapter 9 Choosing the right research design
One-Way Designs • One independent variable • Two groups at a minimum • One-way, multiple-groups design
Factorial Designs • Ins and outs of factorial designs • Main effects • Interactions
Within-Subjects Designs • Between-subjects versus within-subjects • “Repeated measures” design • Advantages of within-subjects designs • Disadvantages of within-subjects designs • Solutions to problems of within-subjects designs
Mixed-Model Designs • At least one independent variable is manipulated between-subjects • At least one independent variable is manipulated within-subjects
One-way design Two-groups design One-way, multiple-groups design Levels of an independent variable Factorial design Main effect Interaction Ordinal (spreading) interaction Disordinal (crossover) interaction Simple effects test Between-subjects design Within-subjects design Repeated measures Key Terms from Chapter 9
Sequence effects Carryover effects Order effects Practice effects Interference effects Counterbalancing Reverse counterbalancing Partial counterbalancing Latin square design Structured debriefing Mixed-model designs Key Terms from Chapter 9
