What is the minimum acceptable IOA percentage recommended in ABA research?
Answer: 80%
A minimum of 80% IOA is the commonly accepted standard to demonstrate adequate measurement reliability in ABA research and practice.
Scatter plot assessments in ABA are used primarily to identify:
Answer: Temporal patterns related to when behaviors occur
Scatter plots reveal patterns in when behaviors are more or less likely to occur throughout the day, helping identify environmental correlates.
Which of the following BEST represents a continuous measurement method?
Answer: Frequency recording of each response
Frequency recording captures every instance of a behavior, making it a continuous (event-based) measurement method rather than a sample-based one.
A BCBA wants to measure behavior magnitude. Which example best illustrates magnitude?
Answer: Loudness of a vocal outburst on a decibel scale
Magnitude refers to the intensity or force of a behavior, such as measuring loudness in decibels or pressure in pounds.
Which data display feature is analyzed to determine if a change in level occurred between two phases?
Answer: The last few data points of one phase compared to the first few of the next
Level change between phases is evaluated by comparing the terminal data points of one phase to the initial data points of the next phase.
What does 'celeration' refer to on a Standard Celeration Chart?
Answer: The rate of change in behavior frequency over time
Celeration is the rate of change in a behavior's frequency, indicating whether responding is accelerating or decelerating across time.
