What is the PRIMARY advantage of using permanent product recording?
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.
Which measure captures the total amount of time a behavior occurs within an observation period?
Answer: Duration
Duration recording measures the total elapsed time from the onset to the offset of a behavior across an observation period.
A behavior analyst notices variability in their data. Which visual analysis feature reflects the degree of data point variability within a phase?
Answer: Variability
Variability describes how much individual data points deviate around the phase's central value or trend line.
IOA (interobserver agreement) is calculated to assess:
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.
Which IOA method divides the number of agreements by the total number of agreements plus disagreements and multiplies by 100?
Answer: Total count IOA
Total count IOA (also called proportion agreement) compares the total counts recorded by each observer, not agreement interval by interval.
When a behavior analyst uses a cumulative graph, the data line can:
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.
