Which of the following is a type of discontinuous measurement?

Discontinuous measurement encompasses methodologies that do not capture every instance of a behavior but instead utilize sampling techniques to record occurrences during specified periods. Whole interval recording, as a type of discontinuous measurement, involves observing whether a behavior occurs throughout the entirety of specific time intervals. For instance, if a behavior occurs for the duration of that interval, it is marked as occurred; if the behavior is not present for the entire interval, it is scored as not occurring. This technique is useful for measuring behaviors that should be maintained over a period, providing a more generalized view of the behavior's occurrence rather than counting each discrete instance.

Frequency, duration, and latency are all continuous measurement techniques, where behaviors are measured in full, either by counting occurrences (frequency), timing the length of behaviors (duration), or measuring the time from a stimulus to the behavior’s initiation (latency). These methods aim to provide precise quantifications of the behavior's extent or timing, rather than sampling occurrences which is the focus of discontinuous methods. Thus, whole interval recording stands out as the correct answer among the options provided.
