Given Jamess multiple responsibilities and limited intermittent observation time continuous measurement methods are not feasible Frequency recording counting every instance of behavior and duration recording measuring the total time a behavior occurs are types of continuous measurement They require the observer to be constantly attentive to the target behavior which James cannot do Whole Interval Recording WIR is a discontinuous measurement procedure where the behavior is recorded as occurring only if it persists throughout the entire predetermined interval This method also demands constant observation during each interval If James is pulled away even for a second he cannot accurately determine if the behavior occurred for the entire interval leading to potential underestimation of the behavior Momentary Time Sampling MTS is the most appropriate discontinuous measurement procedure in this scenario With MTS the observer records whether the behavior is occurring at the exact moment a predetermined interval ends James can set a timer attend to his other students and then only needs to check on the target student when the timer sounds This significantly reduces the demands on the observers attention making it ideal for situations with competing responsibilities MTS provides a reasonable estimate of the behaviors occurrence under these practical constraints
