  1. Whole interval recording scores a behavior as occurring only if:

    Answer: The behavior occurs throughout the entire interval

    Whole interval recording requires the behavior to occur for the entire duration of the interval to be scored as occurring. If the behavior stops at any point during the interval, it is scored as not occurring for that interval.

  2. Which measurement is calculated by dividing the number of responses by the time period?

    Answer: Rate

    Rate (or frequency per unit of time) is calculated by dividing the count of responses by the observation time. For example, 20 responses in 10 minutes = a rate of 2 responses per minute. Rate allows comparison across sessions of different lengths.

  3. An RBT is collecting trial-by-trial data during a discrete trial session. What is being recorded?

    Answer: Whether the response on each trial was correct (+) or incorrect (-)

    Trial-by-trial data involves recording the outcome of each individual trial, typically as correct (+) or incorrect (-). This provides a detailed picture of the learner's performance and allows for calculating percentage correct.

  4. Percentage correct is calculated by:

    Answer: Dividing correct responses by total responses and multiplying by 100

    Percentage correct = (number of correct responses / total number of responses) × 100. For example, 8 correct out of 10 trials = (8/10) × 100 = 80%. This is commonly used to measure skill acquisition progress.

  5. Which type of data collection would be most appropriate for measuring how long a child's tantrum lasts?

    Answer: Duration recording

    Duration recording is most appropriate when the concern is how long a behavior lasts. Tantrums vary in length, and knowing the duration helps determine whether interventions are reducing the length of tantrum episodes.

  6. What is interobserver agreement (IOA)?

    Answer: A measure of the extent to which two independent observers agree on the occurrence of behavior

    Interobserver agreement (IOA) measures the degree to which two or more independent observers record the same data for the same behavior during the same observation period. High IOA suggests the behavioral definition is clear and data are reliable.
