What is the method used to determine the number of intervals in partial interval recording?

The method for determining the number of intervals in partial interval recording involves dividing the total observation time by the length of each interval. This approach allows practitioners to break down the overall observation period into manageable segments, which can help in accurately capturing the occurrences of the target behavior.

For example, if you have a 60-minute observation period and choose to record in 5-minute intervals, dividing 60 by 5 results in 12 intervals. This way, you can systematically monitor behavior across each defined interval, which is crucial for gathering reliable data in ABA practice.

Other methods listed do not reflect the calculation needed for determining intervals; they either involve inappropriate arithmetic operations or do not pertain specifically to defining the structure of observation periods in behavioral data collection.
