3. Compared with the time the behavior really occurs, partial interval recording tends to:
- A.Overestimate the behavior
- B.Underestimate the behavior

- D.Measure only latency
Answer: A. Because one brief occurrence scores the whole interval, partial interval tends to overestimate how much the behavior occurs. It suits behaviors you want to decrease.

4. Why might a supervisor choose momentary time sampling over continuous recording?
- A.It is always more accurate
- B.It counts every response
- C.It takes less effort
- D.It measures latency well
Answer: C. Momentary time sampling only needs a look at the end of each interval, so it frees the technician to teach. It gives an estimate rather than every response.

5. In a multiple-stimulus without replacement (MSWO) assessment, a chosen item is:
- A.Returned to the array
