Which measurement procedure is used for obtaining a tally or count of the number of times a behavior occurs?

• A. Event recording
• B. Duration
• C. Environment
• D. Discrimination training

Answer: (A)

Event recording is the practice of counting every instance of a behavior as it happens, giving you a frequency tally for an observation period. This method directly captures how many times the target behavior occurs, which allows you to compute rate by dividing the count by time if needed. It works best for discrete, clearly identifiable actions, like tapping, shouting, or grabbing an object, because each occurrence is counted as a separate event.

This differs from duration measurement, which tracks how long the behavior lasts, not how many times it happens. The term environment refers to where data are collected, not a method of measuring frequency. Discrimination training is a procedure to teach responses to different stimuli, not a data-collection method for counting occurrences.
