Frequency or Count is a simple measure of how often a particular behavior occurs within a specific time frame. It is one of the most basic methods of data collection in behavior analysis, where each instance of the target behavior is recorded as a count, providing information about how often the behavior is exhibited.
Example
A teacher is tracking how many times a student raises their hand to answer a question during a one-hour lesson. The teacher counts each instance the student raises their hand, and by the end of the lesson, the total count is 5. This frequency data helps the teacher assess how often the student engages in the desired behavior of participating in class.
