Which of the following is a continuous measurement procedure?

• A. Partial Interval
• B. Interresponse Time
• C. Whole Interval
• D. Momentary Time Sample

Answer: (B)

Measuring behavior continuously means capturing data in real time as the behavior occurs, using metrics that vary smoothly rather than just yes/no within fixed slices of time. Interresponse time fits this because it records the exact time between successive responses, giving a continuous measure of the spacing between occurrences. The other methods rely on observations within predefined intervals and produce discrete data: partial interval notes whether the behavior occurred at any point in an interval, whole interval requires it to occur for the entire interval, and momentary time sampling checks whether it’s occurring at the end of each interval. These interval-based methods don’t track the precise timing between responses, so they’re not continuous.
