Which calculation expresses the rate by dividing the number of target responses by the total opportunities and multiplying by 100?

• A. Percent duration
• B. Percent occurrence
• C. Latency
• D. Discontinuous measures

Answer: (B)

Percent occurrence reflects the proportion of opportunities in which the target response occurred, expressed as a percentage. In this approach you count how many times the target behavior happened and divide by the total number of opportunities, then multiply by 100. For example, if there are 10 opportunities and the target response occurs 7 times, the percent occurrence is (7/10) × 100 = 70%. This differs from percent duration, which looks at how long the behavior lasts; latency, which measures the time from a stimulus to the first response; and discontinuous measurement methods, which are sampling procedures rather than a straightforward rate calculation.
