Section 1: Measurement
Continuous Measurement, Discontinuous Measurement, Data Graphing, & Interobserver Agreement (Q1-12)
Q1: An RBT is recording every instance of a client's hand-flapping behavior during a 30-minute session. Each
occurrence is recorded with a tally mark. Which continuous measurement procedure is being used?
A. Duration recording
B. Frequency (event) recording [CORRECT]
C. Partial interval recording
D. Momentary time sampling
Correct Answer: B
Rationale: Frequency (event) recording counts each discrete instance of a behavior that has a clear onset and offset. It is
appropriate for behaviors with a discrete beginning and end, such as hand-flapping, hits, or requests. Choice A (duration)
measures how long the behavior lasts. Choices C and D (partial interval, momentary time sampling) are discontinuous
procedures where observation is divided into intervals and the behavior is recorded only at intervals, not each instance.
Frequency data alone cannot convey rate unless divided by observation time.
Q2: An RBT measures a child's tantrum behavior by recording the total number of minutes the tantrum lasts from
start to finish across the session. Which measurement procedure is being implemented?
A. Frequency recording
B. Duration recording [CORRECT]
C. Latency recording
D. Inter-response time (IRT)
Correct Answer: B
Rationale: Duration recording measures the total time a behavior lasts from onset to offset. It is appropriate for behaviors
that vary in length, such as tantrums, on-task behavior, or play engagement. Choice A (frequency) would count the number
of tantrums, not their length. Choice C (latency) measures the time between a prompt/opportunity and the start of the
behavior. Choice D (IRT) measures the time between consecutive responses. Selecting the wrong procedure distorts data
interpretation.

Q3: An RBT is implementing a measurement procedure where the observation period is divided into 10-second
intervals. The behavior is recorded as occurring in an interval only if it occurs during the ENTIRE interval. Which
discontinuous procedure is this?
A. Partial interval recording
B. Whole interval recording [CORRECT]
C. Momentary time sampling
D. Frequency recording
Correct Answer: B
Rationale: Whole interval recording requires the behavior to occur throughout the entire interval to be scored. It tends to
UNDERESTIMATE the true occurrence of behavior, making it appropriate for measuring continuous behaviors such as
on-task time or engagement. Choice A (partial interval) records behavior if it occurs at ANY point during the interval and
overestimates. Choice C (momentary time sampling) records only at the moment the interval ends. Choice D is a
continuous, not discontinuous, procedure.
Q4: An RBT records whether a client is engaged in appropriate play at the exact moment the timer sounds at the
end of each 30-second interval. The RBT does not track the behavior between timer soundings. Which
measurement procedure is being used?
A. Partial interval recording
B. Whole interval recording
C. Momentary time sampling (MTS) [CORRECT]
D. Continuous frequency recording
Correct Answer: C
Rationale: Momentary time sampling (MTS) records occurrence or non-occurrence of behavior at a single instant —
typically when a timer sounds at the end of each interval. MTS is practical for continuous measurement when continuous
observation is impractical and tends to neither systematically over- nor underestimate. Choice A (partial) records behavior
occurring at any point in the interval. Choice B (whole) requires behavior throughout the interval. Choice D is continuous
and impractical for the timer-sound approach described.
Q5: Two RBTs independently record the frequency of a client's hand-raising behavior during a 30-minute session.
Observer 1 records 15 occurrences; Observer 2 records 12 occurrences. Using the frequency-count method of
interobserver agreement (IOA), what is the agreement percentage?
A. 80% [CORRECT]
B. 75%
C. 90%
D. 100%
Correct Answer: A
Rationale: Frequency-count IOA is calculated as: (smaller count / larger count) × 100 = () × 100 = 80%. The
standard threshold for acceptable IOA is 80% or higher (some standards require 85% for newer observers). Choice B
(75%) is incorrect arithmetic. Choice C (90%) and D (100%) are not derived from the formula. Low IOA indicates
measurement unreliability and requires retraining or procedural clarification.

Q6: An RBT records the following data: 'During the session, the client tantrummed several times when prompted
to transition.' Which statement BEST explains the problem with this session note?
A. The note is too short; session notes must be at least 200 words
B. The note uses subjective, non-operational language ('tantrummed several times') instead of objective,
measurable, observable behavior definitions [CORRECT]
C. The note should not mention behavior problems
D. Session notes are not required if data sheets are completed
Correct Answer: B
Rationale: Session notes must be objective, observable, and measurable. 'Tantrummed several times' is vague and
unquantifiable. The RBT should rewrite using the operational definition, e.g., 'Client engaged in crying, dropping to floor,
and swiping materials on 3 of 5 transition trials.' Choice A is wrong: there is no word count rule. Choice C is wrong:
behavior problems can and should be documented objectively. Choice D is wrong: session notes are required to provide
qualitative context beyond data sheets.
Q7: A client exhibits 6 instances of aggression during a 10-minute observation. What is the rate of behavior per
minute?
A. 0.6 per minute [CORRECT]
B. 1.67 per minute
C. 6 per minute
D. 60 per minute
Correct Answer: A
Rationale: Rate = frequency / observation time = = 0.6 responses per minute. Rate is preferred over raw frequency
when observation time varies between sessions because it allows comparison. Choice B inverts the formula. Choice C is
raw frequency, not rate. Choice D is incorrect arithmetic. The BACB Task List (2nd Ed.) requires RBTs to calculate and
report rate when using frequency measures.
Q8: An RBT is measuring a client's compliance with a 'clean up' instruction by recording the time from the prompt
to the start of the cleaning behavior. Which measurement procedure is being used?
A. Duration
B. Latency [CORRECT]
C. Inter-response time
D. Trial-by-trial frequency
Correct Answer: B
Rationale: Latency measures the time elapsed between the presentation of a stimulus (e.g., prompt, instruction) and the
initiation of the behavior. It is appropriate for measuring response to prompts and compliance. Choice A (duration)
measures how long the behavior lasts. Choice C (IRT) measures the time between consecutive responses. Choice D
(trial-by-trial frequency) records whether a behavior occurred on each trial.
