Disadvantage is that measurement can over or under estimate behavior. Remember, FREQUENCY=COUNT. Supervisees need to understand how to calculate percent of occurrence as well as the advantages and disadvantages of this method. A percentage presents a proportional quantity per 100 (Cooper, Heron, & Heward, 2007). ABA Therapy Monday, February 24, 2014. A-07 - Measure trials to criterion. Percent of occurrence is a derivative measure of correct responses over a set number of opportunities. 3 0 obj
: The probability of one event given some other event (e.g., if responses A and B occur equally often but A is followed by A 75 percent of the time and by B 25 percent of the time, the simple probability of A is 0.5, whereas its conditional probability given that the last response was A is.75).

A-06 Measure percent of occurrence. To calculate the percentage, the sum of the times (duration) that the behavior occurred is divided by the total observation time (For example, if the behavior was displayed for a total of 10 minutes during your 30 minute observation of the student, the behavior was happening 33% of the time). These ABA data sheets include input forms for ten and twenty trials to track particular actions. Section 1. Frequency, Rate, Duration, Latency, and Interresponse Time Fourth Edition Task List. endobj
