Let’s look at a graph. This graph represents the number of times my cat scratches the couch. Remember that in baseline, I’m yelling at her every time she scratches the couch. This is what the data look like.
Measure the behavior repeatedly in the baseline phase.
Implement the intervention and measure the behavior repeatedly in the intervention phase.
GRAPH the data and use VISUAL ANALYSIS to decide if the intervention caused a change in the behavior.
