What is the definition of discontinuous measurement?

Discontinuous measurement refers to a method of collecting data where only a portion or sample of instances of a behavior is recorded, rather than documenting every occurrence throughout the entire observation period. This approach allows practitioners to capture specific instances of behavior without needing to observe continuously.

In practical terms, discontinuous measurement is useful in scenarios where continuous observation is not feasible due to time constraints or the need to focus on particular incidents of a behavior. For example, a practitioner may choose to observe and record behaviors at predetermined intervals, effectively sampling behavior occurrences rather than tracking each instance. By using this method, valuable insights can still be obtained while managing the resources required for data collection.

The other options involve either complete or exhaustive recording of behavior or imply that no behavior is recorded, which do not align with the intended definition of discontinuous measurement.
