Recording occurrence/non-occurrence at a specific point in time describes which measurement approach?

• A. Discontinuous measurement procedures
• B. Continuous measurement procedures
• C. Permanent product recording procedures
• D. Enter data and update graphs

Answer: (A)

Recording occurrence/non-occurrence at a specific point in time is a hallmark of discontinuous measurement procedures. In this approach, data are collected only at particular moments or intervals rather than watching and recording every instance as it happens. Checking whether a behavior is occurring at a single, predetermined moment is a classic example—known as momentary time sampling—which yields a yes/no answer for that instant. This differs from continuous measurement, which tracks every instance of the behavior as it occurs, providing detailed counts, durations, or rates. Permanent product recording focuses on the tangible outcome of the behavior rather than its moment-to-moment occurrence, and “enter data and update graphs” describes data management, not a measurement method.
