Which measurement approach involves recording every instance of a behavior as it occurs?
Partial interval recording
Continuous measurement
Discontinuous measurement
Momentary time sampling
Continuous measurement captures each occurrence of a target behavior during an observation period, allowing for precise event recording and analysis. It contrasts with discontinuous methods that sample behavior at specific times. Continuous approaches include frequency, duration, latency, and interresponse time measurements. Learn more in the BACB RBT Task List .
Which measurement dimension standardizes the number of responses per unit of time?
Rate
Frequency
Latency
Duration
Rate refers to the count of responses per standard unit of time, combining frequency and time in a single metric. Unlike raw frequency, rate provides clarity on how often a behavior occurs relative to session length. It is commonly expressed as responses per minute or hour. See the BACB RBT Task List for more information .
Which of the following is an example of permanent product measurement?
Number of verbal requests
Latency to task initiation
Completed worksheets
Duration of crying spells
Permanent product measurement records tangible outcomes produced by behavior, such as completed worksheets or written work. It does not require observation of the behavior in real time. This method is efficient when direct observation is impractical or errors are unlikely by using the product itself. Additional details are available in the BACB RBT Task List .
Which data collection method involves dividing the observation period into equal intervals and recording whether the behavior occurs at the end of each interval?
Whole interval recording
Duration recording
Partial interval recording
Momentary time sampling
Momentary time sampling divides an observation session into equal intervals and records if the target behavior is occurring precisely at the end of each interval. This method provides an estimate of behavior occurrence and is efficient for high-rate or continuous behaviors. It does not capture every instance but offers a representative sample. More on this method can be found in the BACB RBT Task List .
When is partial interval recording the most appropriate measurement method?
When behaviors occur at high rates and are brief
For low-frequency behaviors
When a permanent product is available
To measure the latency of a response
Partial interval recording is used when behaviors occur at high rates or brief durations, making continuous measurement impractical. It records whether the behavior occurred at any time during each interval and can overestimate total duration. This method is efficient but less precise than continuous recording. Refer to the BACB RBT Task List for guidance .
What is the primary purpose of interobserver agreement (IOA) in measurement?
To measure the trend of behavior change
To record behavior at specific time points
To calculate interresponse time
To assess consistency between observers
Interobserver agreement (IOA) assesses the consistency and reliability of data collected by two independent observers. High IOA indicates that measurement procedures are clearly defined and implemented consistently. It is a critical component of valid and trustworthy behavioral assessment. For more details, see the BACB RBT Task List .
Which measurement dimension assesses the time between the delivery of an antecedent and the initiation of the behavior?
Interresponse time
Rate
Duration
Latency
Latency measures the time elapsed between a specific antecedent stimulus and the initiation of the target behavior. It is used to evaluate promptness and responsiveness to instructions or cues. This dimension is essential for assessing behavioral modifications that affect promptness. Additional information is available in the BACB RBT Task List .
Which type of graph is most commonly used to display behavior data over time in applied behavior analysis?
Bar graph
Line graph
Cumulative record
Scatterplot
Line graphs are the standard in applied behavior analysis for displaying frequency, rate, and other continuous measurement data over time. They clearly show level, trend, and variability across sessions or phases. Line graphs facilitate visual analysis and the detection of behavior changes. Refer to the BACB RBT Task List for more examples .
A client engages in self-stimulatory behavior 15 times during a 10-minute session. What is the rate of this behavior per minute?
1.5
0.67
0.15
15
Rate is calculated by dividing the total number of responses by the duration of the session in minutes. In this case, 15 occurrences divided by 10 minutes equals 1.5 responses per minute. Rate standardizes the behavior count, making data comparable across sessions of different lengths. For formula details, see the BACB RBT Task List .
Which measurement dimension is defined as the time between the end of one response and the beginning of the next?
Rate
Interresponse time
Duration
Latency
Interresponse time (IRT) measures the elapsed time between two consecutive responses, capturing the spacing of behavior over time. It provides insight into the pattern and pace of responding. Short IRTs indicate rapid succession, while long IRTs reflect extended pauses. More on IRT can be found in the BACB RBT Task List .
Partial interval recording often results in which type of measurement artifact?
Underestimation of total behavior duration
Exact measurement with no bias
Overestimation of total behavior duration
Random measurement error
Partial interval recording marks an interval if the behavior occurred at any time during that interval, which can overestimate the actual total duration of behavior. It is more sensitive to brief, high-rate behaviors but sacrifices precision. This artifact can lead to inflated estimates of occurrence. Learn more about discontinuous measurement artifacts in the BACB RBT Task List .
Whole interval recording typically produces which measurement artifact?
Overestimation of total behavior duration
Underestimation of total behavior duration
Exact measurement with no bias
Improved interobserver agreement
Whole interval recording only records intervals where the behavior occurs throughout the entire interval, often underestimating the actual duration if the behavior starts or ends within intervals. This method is best for high-frequency, continuous behaviors but can miss brief occurrences. It sacrifices sensitivity for a more conservative estimate. For further discussion, see the BACB RBT Task List .
According to BACB guidelines, what is the minimum interobserver agreement (IOA) percentage required to ensure data reliability?
95%
80%
70%
90%
The BACB recommends a minimum IOA of 80% to ensure that data are reliable and measurement procedures are implemented consistently. Achieving at least 80% agreement helps validate that the observed changes in behavior are not due to measurement error. Higher IOA levels are encouraged for critical decision-making or variable behaviors. Refer to the BACB RBT Task List for official standards .

Cheat Sheet

  1. Continuous Measurement: Frequency and Rate -

    Understand that frequency (count) and rate (count divided by observation time) are core to any behavioral data collection quiz, as outlined in Cooper, Heron, & Heward (2007). For example, if a learner raises their hand 15 times in 10 minutes, their rate is 1.5 responses per minute. A helpful mnemonic is "count then divide to thrive" when tackling measurement exam items.

  2. Duration Measurement -

    Duration records the total time a behavior occurs, which is vital for continuous measurement RBT practice. For instance, if a tantrum lasts for 4.2 minutes, you log 4 minutes and 12 seconds of occurrence. Remember "start to stop, give it a stopwatch" to ace duration questions on a measurement quiz RBT style.

  3. Latency and Inter-Response Time (IRT) -

    Latency measures the time from stimulus to response, while IRT tracks the interval between consecutive responses (Cooper et al., 2007). For example, if the learner takes 5 seconds to comply after an instruction, latency is 5 seconds; if the next request comes 12 seconds later, that's the IRT. These metrics often appear in RBT measurement questions assessing promptness and pacing.

  4. Interval Sampling Methods -

    Partial-interval, whole-interval, and momentary time sampling each offer trade-offs for busy practitioners. In a 10-second interval, momentary sampling checks only at the end, while partial records any occurrence, and whole requires continuous occurrence. Familiarize yourself with each method to confidently tackle the behavioral data collection quiz and know when each is most reliable.

  5. Interobserver Agreement (IOA) -

    IOA gauges reliability by comparing observers' data: IOA (%) = (Agreements ÷ [Agreements + Disagreements]) × 100 (BACB, 2023). Aim for at least 80% agreement to meet professional standards. Mastering this formula ensures success on rbt measurement questions about data integrity.
