ABAT - Applied Behavior Analysis Measurement and Data Collection Questions and Answers 3 — Questions and Answers
Question 1: A behavior analyst wants to measure the number of times a student raises their hand during a 30-minute class. Which measurement dimension is being captured?
- Duration
- Frequency (Correct answer)
- Latency
- Interresponse time
Correct answer: Frequency
Frequency (count) measures how many times a behavior occurs within an observation period.
Question 2: Which data collection method involves dividing an observation session into equal intervals and recording whether the behavior occurred at any point during each interval?
- Whole-interval recording
- Partial-interval recording (Correct answer)
- Momentary time sampling
- Event recording
Correct answer: Partial-interval recording
Partial-interval recording scores an interval as positive if the behavior occurs at any time during the interval, which tends to overestimate behavior.
Question 3: A therapist measures the time from when an instruction is given to when the child begins to comply. This is a measure of:
- Duration
- Magnitude
- Latency (Correct answer)
- Interresponse time
Correct answer: Latency
Latency is the elapsed time between the onset of a stimulus (instruction) and the initiation of the response.
Question 4: When using a scatterplot to analyze behavioral data, the primary purpose is to:
- Calculate the mean rate of behavior
- Identify temporal patterns and correlations with time of day or activity (Correct answer)
- Determine the function of behavior
- Measure the duration of each episode
Correct answer: Identify temporal patterns and correlations with time of day or activity
Scatterplots display data across time blocks to reveal patterns showing when behavior is more or less likely to occur.
Question 5: Interobserver agreement (IOA) is best described as:
- The consistency of a single observer across multiple sessions
- The degree to which two or more independent observers record the same data simultaneously (Correct answer)
- The agreement between a behavior analyst and the client's family
- The reliability of a measurement instrument over time
Correct answer: The degree to which two or more independent observers record the same data simultaneously
IOA assesses measurement reliability by comparing data collected independently by two observers at the same time.
Question 6: Which formula is used to calculate exact count IOA for frequency data?
- Smaller count / Larger count × 100 (Correct answer)
- (Agreements / Total intervals) × 100
- (Total agreements / Total observations) × 100
- Mean of observer 1 / Mean of observer 2 × 100
Correct answer: Smaller count / Larger count × 100
Exact count IOA divides the smaller frequency count by the larger and multiplies by 100 to get a percentage.
Question 7: A behavior that has a clear beginning and end, making it easy to count discrete occurrences, is best described as having:
- High magnitude
- Clear topography
- A discrete response unit (Correct answer)
- Continuous duration
Correct answer: A discrete response unit
Discrete behaviors have distinguishable starts and stops, making frequency-based measurement practical and reliable.
