SECTION 1: Measurement (Q1-Q13)
Continuous Measurement, Discontinuous Measurement, Data Graphing, and Interobserver Agreement
Q1: Which measurement procedure records each instance of a behavior as a simple tally count, without
reference to the time during which it occurred?
A. Duration recording
B. Frequency recording [CORRECT]
C. Latency recording
D. Momentary time sampling
Correct Answer: B
Rationale: Frequency is the simplest continuous measure: a tally of each instance of the response (Task List
A-2). Duration measures how long each instance lasts, latency measures the time from instruction to response
onset, and momentary time sampling is a discontinuous estimation procedure rather than a true count. Study note:
when a stem says tally or count, frequency is almost always the answer.
Q2: An RBT records 24 instances of hand-flapping during a 3-hour session. To report rate, which value
should the RBT calculate?
A. 3 instances per hour
B. 12 instances per hour
C. 8 instances per hour [CORRECT]
D. 24 instances per session
Correct Answer: C
Rationale: Rate expresses frequency relative to observation time: 24 instances divided by 3 hours equals 8
instances per hour, which allows comparison across sessions of different lengths (Task List A-2). Option D
reports a raw frequency rather than a rate, and options A and B reflect common division errors in which time is
divided by count. Study note: always divide count by time, never the reverse.

Q3: A BCBA asks the RBT to measure how long each tantrum lasts from onset to offset. Which
measurement procedure should the RBT use?
A. Duration per occurrence recording [CORRECT]
B. Frequency recording
C. Inter-response time recording
D. Partial interval recording
Correct Answer: A
Rationale: The question asks how long the behavior lasts, which defines duration per occurrence recording:
timing from behavior onset to behavior offset (Task List A-2). Frequency would ignore the length of each
tantrum, inter-response time measures gaps between responses, and partial interval is a discontinuous estimate.
Study note: how long equals duration, one of the most reliably tested measurement matches.
Q4: The RBT says the instruction touch your nose and starts a timer; the learner complies 6 seconds
later. What did the RBT measure?
A. Duration of compliance
B. Inter-response time
C. Response rate
D. Latency [CORRECT]
Correct Answer: D
Rationale: Latency is the elapsed time between the presentation of a stimulus, such as an instruction, and the
onset of the response (Task List A-2). Duration would measure how long the nose-touch lasted, inter-response
time measures gaps between successive responses, and rate requires a count across observation time. Study note:
latency starts at the instruction, not at the response.
Q5: During a 30-minute observation, an RBT records the amount of time that passes between the end of
one instance of vocal stereotypy and the beginning of the next. Which measure is being recorded?
A. Latency
B. Inter-response time [CORRECT]
C. Whole interval recording
D. Frequency
Correct Answer: B
Rationale: Inter-response time (IRT) is the elapsed time between two successive responses and is often used
when increasing the time between occurrences of a behavior is the goal (Task List A-2). Latency measures
instruction-to-response time, whole interval is a discontinuous procedure, and frequency ignores the time
dimension entirely. Study note: time between responses equals IRT, time from instruction to response equals
latency - this commonly confused pair appears on nearly every exam.
Q6: Which discontinuous measurement procedure tends to OVERestimate the occurrence of a
behavior?
A. Momentary time sampling
B. Whole interval recording
C. Partial interval recording [CORRECT]
D. Permanent product recording
Correct Answer: C

Rationale: In partial interval recording the observer marks the interval if the behavior occurs at any point during
it, which systematically overestimates occurrence (Task List A-3). Whole interval requires occurrence throughout
the interval and underestimates, momentary time sampling checks only the interval end and has no consistent
directional bias, and permanent product recording measures lasting outcomes rather than live behavior. Study
note: memorize partial over, whole under, momentary mixed.
Q7: An RBT divides a 10-minute observation into 20-second intervals and marks an interval only if the
on-task behavior occurs for the ENTIRE interval. Which procedure is this?
A. Whole interval recording [CORRECT]
B. Partial interval recording
C. Momentary time sampling
D. Duration recording
Correct Answer: A
Rationale: Whole interval recording requires the behavior to persist throughout the entire interval, which
produces an underestimate and is often chosen for behaviors the team wants to increase, such as on-task
engagement (Task List A-3). Partial interval marks any occurrence, momentary time sampling records only the
interval end, and duration is a continuous measure. Study note: entire or whole time in the stem signals whole
interval.
Q8: A classroom RBT can only glance up from instruction every 2 minutes to see whether a student is
out of his seat. Which procedure best matches this observation style?
A. Whole interval recording
B. Partial interval recording
C. Frequency counting
D. Momentary time sampling [CORRECT]
Correct Answer: D
Rationale: Momentary time sampling records whether the behavior is occurring at the exact moment each
interval ends and requires the least continuous observation effort, making it practical in busy settings (Task List
A-3). Whole and partial interval require watching throughout each interval, and frequency requires counting every
instance. Study note: when a stem emphasizes limited attention or glancing at the end of intervals, choose
momentary time sampling.
Q9: A team wants to track increasing engagement during seatwork and needs a discontinuous estimate
that will NOT inflate apparent progress. Which procedure and bias combination is most appropriate?
A. Partial interval recording, which underestimates occurrence
B. Momentary time sampling, which overestimates occurrence
C. Frequency recording, which overestimates occurrence
D. Whole interval recording, which underestimates occurrence [CORRECT]
Correct Answer: D
Rationale: Whole interval recording requires the behavior to persist the entire interval, so it systematically
underestimates occurrence and is conservative for tracking skill gains such as engagement (Task List A-3). Partial
interval overestimates, momentary time sampling has no consistent bias, and frequency is a continuous count
rather than a discontinuous estimate. Study note: match the direction of the bias to the goal of the program.
