Whole Interval Recordingย is a data collection method used to observe whether aย behaviorย occurs throughout an entire predetermined interval. If theย behaviorย is present for the entire interval, it is marked as occurring; if theย behaviorย occurs only for part of the interval or not at all, it is marked as absent. This method often underestimates the totalย durationย ofย behavior.
Example
A teacher observes a student during a 10-second interval to determine if the student stays seated for the entire time. If the student remains seated for the whole 10 seconds, theย behaviorย is recorded as occurring. If the student stands up or moves before the 10 seconds are over, theย behaviorย is not recorded as present.
