ABA Measurement and Data Collection 2 — Questions and Answers
Question 1: What is the PRIMARY advantage of using permanent product recording?
- It does not require direct observation during behavior (Correct answer)
- It captures duration of each behavior
- It measures behavior topography
- It requires no baseline data
Correct answer: It does not require direct observation during behavior
Permanent product recording measures the tangible outcomes left by a behavior, allowing data to be collected without continuous direct observation.
Question 2: Which measure captures the total amount of time a behavior occurs within an observation period?
- Duration (Correct answer)
- Frequency
- Latency
- Rate
Correct answer: Duration
Duration recording measures the total elapsed time from the onset to the offset of a behavior across an observation period.
Question 3: A behavior analyst notices variability in their data. Which visual analysis feature reflects the degree of data point variability within a phase?
- Level
- Trend
- Variability (Correct answer)
- Overlap
Correct answer: Variability
Variability describes how much individual data points deviate around the phase's central value or trend line.
Question 4: IOA (interobserver agreement) is calculated to assess:
- The reliability and accuracy of the measurement system (Correct answer)
- Whether the intervention is effective
- The social validity of the target behavior
- The function of the behavior
Correct answer: The reliability and accuracy of the measurement system
IOA is computed to evaluate the consistency between two independent observers, ensuring the measurement system is reliable.
Question 5: Which IOA method divides the number of agreements by the total number of agreements plus disagreements and multiplies by 100?
- Occurrence IOA
- Nonoccurrence IOA
- Total count IOA (Correct answer)
- Exact count-per-interval IOA
Correct answer: Total count IOA
Total count IOA (also called proportion agreement) compares the total counts recorded by each observer, not agreement interval by interval.
Question 6: When a behavior analyst uses a cumulative graph, the data line can:
- Only go up or remain flat, never decrease (Correct answer)
- Go up and down freely
- Reset to zero each session
- Show rate automatically without calculation
Correct answer: Only go up or remain flat, never decrease
Cumulative records add each new data point to the previous total, so the line never decreases unless the behavior rate drops to zero.
