Study Notes
Discontinuous Data Collection Methods
- Momentary Time Sampling (MTS): Records occurrences of behavior at the end of a specific interval, marking if the behavior is present at that precise moment.
- Partial Interval Recording: Marks the behavior if it occurs at any point during the interval; can lead to overestimation of behavior.
- Whole Interval Recording: Marks the behavior only if it occurs throughout the entire duration of the interval; tends to underestimate behavior occurrence.
Important Concepts
- PLA-CHECK: Recognized for underestimating behavior, indicating a potential limitation in certain observation methods.
- MTS for Groups: Utilizes the PLA-CHECK method to monitor the behavior of groups, characterized as a headcount approach.
General Observations
- Whole interval recording is associated with conservative estimates of behavior, meaning it more likely misses short occurrences.
- Partial interval recording is likely to provide inflated behavior counts, due to its measurement approach.
