ABA Measurement and Data Collection 2

Question 1

What is the PRIMARY advantage of using permanent product recording?

Accepted Answer

It does not require direct observation during behavior

Answer

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?

Accepted Answer

Duration

Answer

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?

Accepted Answer

Variability

Answer

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:

Accepted Answer

The reliability and accuracy of the measurement system

Answer

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?

Accepted Answer

Total count IOA

Answer

Total count IOA (also called proportion agreement) compares the total counts recorded by each observer, not agreement interval by interval.
