  1. A client engages in self-injurious behavior (SIB) that occurs in rapid bursts making it impossible to count each instance individually. Which measurement system is MOST appropriate?

    Answer: Partial interval recording

    Partial interval recording is best for behaviors occurring in rapid bursts that are difficult to count individually, as it captures whether the behavior occurred at any point during each interval.

  2. During a 30-minute session, a client's appropriate play behavior was observed during 18 of 30 intervals using whole interval recording. What is the percentage of intervals?

    Answer: 60%

    Percentage = (intervals with behavior / total intervals) × 100 = (18/30) × 100 = 60%.

  3. An RBT is using momentary time sampling with 1-minute intervals over a 10-minute observation. The client is on-task at the moment of observation in 6 of 10 intervals. What does this tell us?

    Answer: The client was on-task at 60% of the sampled time points

    Momentary time sampling only reflects what is happening at the exact moment of observation, not the total duration of the behavior.

  4. Which data collection method would BEST capture the number of words spoken by a client during a language intervention session?

    Answer: Frequency recording

    Frequency recording counts the number of discrete occurrences, making it ideal for tallying individual words spoken.

  5. An RBT records the time from when an instruction is given to when the client begins the response. This is called:

    Answer: Latency recording

    Latency recording measures the time elapsed between the presentation of a stimulus (instruction) and the initiation of the response.

  6. A supervisor reviews an RBT's data sheet and notices behavior was marked as occurring during every interval of a session. The supervisor suspects the RBT may have engaged in:

    Answer: Drift

    Drift occurs when an observer's recording gradually deviates from the original operational definition, often resulting in inaccurate data over time.

  7. Which of the following BEST describes a continuous measurement system?

    Answer: Every occurrence of the behavior is recorded throughout the observation period

    Continuous measurement means every single instance of the target behavior is recorded throughout the entire observation period without sampling.
