In Applied Behavior Analysis (ABA), level refers to the value on the vertical axis (y-axis) of a graph that represents the degree or magnitude of a behaviorBehavior refers to any activity or action that living organisms engage in, which can be observed, measured, and analyzed. It encompasses all interactions an organism has with its environment, inc... More. It indicates the average rateRate refers to the number of times a behavior occurs within a specific time period. It is calculated by dividing the frequency of the behavior by the length of time observed, allowing for a standardiz...

When analyzing data in ABA, level helps assess whether behavior is occurring at a high, low, or moderate rate.
Example
A behavior analyst is tracking how often a student raises their hand during class. During the baseline phase, the student raises their hand an average of 2 times per class period. After introducing a reinforcementReinforcement is a fundamental concept in Applied Behavior Analysis (ABA) and behavioral psychology. It refers to any consequence that follows a behavior and increases the likelihood that the behavior... More strategy, the level of hand-raising increases to an average of 6 times per class period. The change in level (from 2 to 6) shows that the intervention had an effect on the behavior, increasing the frequency of hand-raising.
