Making a judgment about the effects of an intervention by examining graphed data is a crucial aspect of data analysis in applied behavior analysis. Graphs provide a visual representation of data over time, allowing practitioners to observe trends, patterns, and potential changes in behavior more clearly than raw data or anecdotal observations. This visualization helps to interpret whether an intervention is effective, as it highlights fluctuations and shifts in the behaviors being measured in a straightforward and comprehensible manner.

The use of graphed data is foundational in evaluating interventions because it helps to support evidence-based decisions. By analyzing graphed data, practitioners can assess progress, identify when an intervention needs to be modified, or determine if the response to an intervention is stable or varied.

In the context of behavior analysis, relying solely on raw data or anecdotal evidence does not provide the same clarity or insight that a graphical representation can. The use of graphed data allows for a more objective and precise understanding of the effects and effectiveness of the interventions being implemented.
