What does percent occurrence measure in terms of a behavior?

Percent occurrence specifically measures the proportion of opportunities in which a particular behavior occurs out of the total chances available for that behavior to happen. This measurement provides insight into the frequency of the behavior in relation to the situations or contexts that allow for the behavior to be emitted.

For instance, if a child has the opportunity to engage in a certain behavior 10 times during a session and they do so 7 times, the percent occurrence would indicate a 70% occurrence rate. This helps practitioners assess how often the behavior is being emitted in the appropriate contexts, making it a valuable tool for understanding and evaluating behavior in a structured manner.

This measurement contrasts with other options that focus more broadly on frequency without contextual proportion, overall performance which lacks specificity, or correctness which does not consider opportunity but rather accuracy alone.
