Final answer:
A Multiple Baseline Design across skills or settings is a research design used to evaluate the effectiveness of an intervention by implementing it sequentially across different skills or settings. It allows for the comparison of changes in skills or settings over time.
Step-by-step explanation:
A Multiple Baseline Design across skills or settings is a research design used to evaluate the effectiveness of an intervention. It involves implementing the intervention sequentially across different skills or settings and observing the effects. By measuring the outcomes before and after the intervention, researchers can determine if the intervention had a positive impact. For example, in a study targeting reading skills, the intervention may be implemented in different classrooms, and the progress in reading skills is measured before and after the intervention. This design allows for a comparison of changes in skills or settings over time and provides evidence of the effectiveness of the intervention.
