Final Answer:
In the context of Multiple Baseline design, the Independent Variable (IV) should not be applied to the next behavior until stability or baseline has been established in the initial behavior.
Step-by-step explanation:
The phrase "Multiple Baseline" refers to a research design often used in applied behavior analysis and behavioral psychology. In this design, multiple behaviors, individuals, or settings are measured over time to establish a baseline before introducing an intervention or treatment. The critical principle is to ensure that the Independent Variable (IV), which is the intervention, is not applied to the next behavior until stability or baseline has been established in the initial behavior. This sequential approach helps to isolate the effects of the intervention on each behavior, allowing for a clearer understanding of its impact.
It is essential to follow this methodological rigor to draw valid conclusions about the effectiveness of the intervention in behavior analysis studies.
