In behavior analysis, what does 'accuracy' measure?

In behavior analysis, accuracy specifically refers to the degree to which the performance of a behavior matches the desired or correct standard. This means measuring how correctly a behavior is executed in comparison to established criteria or benchmarks. For example, when teaching a student to perform a task, accuracy would assess whether each component of that task was completed correctly according to the instructional guidelines. This measurement facilitates the evaluation of an individual's skill level and provides insights into areas that may need improvement or further instruction.

The other options describe different aspects of behavior measurement. The total number of behaviors performed would quantify frequency, duration pertains to how long a behavior occurs, and intensity focuses on the power or severity of the behavior itself. While all these measures can be important in a comprehensive analysis, they do not specifically address the correctness of behavior execution, which is the essence of what accuracy measures.
