ABA Measurement and Data Collection 1 — Questions and Answers
Question 1: Which data collection method involves recording whether a behavior occurred at least once during an observation interval?
- Partial interval recording (Correct answer)
- Whole interval recording
- Momentary time sampling
- Frequency recording
Correct answer: Partial interval recording
Partial interval recording scores a behavior as occurred if it happens at any point within the interval, regardless of duration.
Question 2: A BCBA wants to measure the time between the end of one response and the beginning of the next. What is this called?
- Inter-response time (IRT) (Correct answer)
- Latency
- Duration
- Rate
Correct answer: Inter-response time (IRT)
Inter-response time (IRT) is the elapsed time between the end of one response and the onset of the next response.
Question 3: Which measurement dimension refers to the number of responses per unit of time?
- Rate (Correct answer)
- Frequency
- Duration
- Magnitude
Correct answer: Rate
Rate is frequency divided by time (responses per minute or hour), capturing both how often and how quickly behavior occurs.
Question 4: Momentary time sampling is BEST suited for measuring behaviors that are:
- Ongoing or state behaviors (Correct answer)
- Brief and discrete
- Dangerous and high-rate
- Novel and low-frequency
Correct answer: Ongoing or state behaviors
Momentary time sampling records whether a behavior is occurring at the exact moment the interval ends, making it ideal for continuous, state-like behaviors.
Question 5: A therapist records the time from the presentation of a discriminative stimulus to the beginning of the learner's response. This is called:
- Latency (Correct answer)
- Duration
- Inter-response time
- Magnitude
Correct answer: Latency
Latency measures the elapsed time between the onset of an antecedent stimulus and the start of the target response.
Question 6: Which graph type is most commonly used to display continuous behavioral data over time in ABA?
- Simple line graph (Correct answer)
- Bar graph
- Pie chart
- Scatter plot
Correct answer: Simple line graph
Simple line graphs display data points connected sequentially, making it easy to visualize trends and changes in behavior over sessions.
