Final answer:
The dimension of ABA being described here is Analytical, as it involves the analysis of collected data to determine the effectiveness of the intervention.
Step-by-step explanation:
The given scenario describes the dimension of Analytical in Applied Behavior Analysis (ABA).
ABA involves conducting systematic assessments and collecting data to determine if the intervention is effective in changing behavior. In this case, the behavior plan designed by Christiane included data collection before intervention, during intervention, and during a brief removal of the intervention. By comparing the data, Christiane was able to analyze and determine that the intervention alone caused the desired change in behavior.
Therefore, the dimension of ABA being described here is Analytical, as it involves the analysis of collected data to determine the effectiveness of the intervention.
