In point in time sampling, behavior is counted when?

Point in time sampling is a specific observational method used to assess behavior by focusing on specific moments in time during an observation period. The correct choice highlights that a behavior is counted when it is present at the end of each interval. This means that observers make judgments about whether the behavior is occurring at that predetermined point in time, facilitating a snapshot assessment of behaviors.

This method contrasts with continuous sampling, where behaviors are tracked throughout the entire interval. Point in time sampling specifically aims to capture whether a behavior is happening at the exact end moment of the interval, providing a clear and defined method for counting occurrences without the necessity of constant recording throughout the entire period. The design allows for efficient monitoring and is often used in settings where time is limited or when specific instances are crucial for data collection.
