A continuous form of data collection that is a measure of the length of a response.

• A. Latency
• B. Interresponse Time
• C. Frequency
• D. Duration

Answer: (D)

Measuring how long a response lasts is a duration measure, a continuous data collection that records the actual time the behavior occupies from start to finish. Duration captures the length of the response in units like seconds, giving a precise, continuous value for how long the behavior persists. Latent time would tell you how long it takes to start the response after a stimulus, which is about initiation rather than how long the response lasts. Interresponse time measures the gap between consecutive responses, focusing on pauses between actions rather than the duration of a single action. Frequency counts how many times the behavior occurs in a period, which tells about occurrence rate but not how long each instance lasts. So, when the question asks for the measure of the length of a response, duration is the best fit. For example, if a child on task continues a task for 5 seconds, duration records that 5-second period.
