Once a baseline of behavior has been established (when a consistent pattern emerges with at least three data points), the intervention begins.

In this example, we can see that the frequency of disruptions decreased once praise began.

Another design is the A-B-A design. An A-B-A design (also known as a reversal design) involves discontinuing the intervention and returning to a baseline.
