ABA Measurement and Data Collection 3

Question 1

What is the minimum acceptable IOA percentage recommended in ABA research?

Accepted Answer

80%

Answer

A minimum of 80% IOA is the commonly accepted standard to demonstrate adequate measurement reliability in ABA research and practice.

Question 2

Scatter plot assessments in ABA are used primarily to identify:

Accepted Answer

Temporal patterns related to when behaviors occur

Answer

Scatter plots reveal patterns in when behaviors are more or less likely to occur throughout the day, helping identify environmental correlates.

Question 3

Which of the following BEST represents a continuous measurement method?

Accepted Answer

Frequency recording of each response

Answer

Frequency recording captures every instance of a behavior, making it a continuous (event-based) measurement method rather than a sample-based one.

Question 4

A BCBA wants to measure behavior magnitude. Which example best illustrates magnitude?

Accepted Answer

Loudness of a vocal outburst on a decibel scale

Answer

Magnitude refers to the intensity or force of a behavior, such as measuring loudness in decibels or pressure in pounds.

Question 5

Which data display feature is analyzed to determine if a change in level occurred between two phases?

Accepted Answer

The last few data points of one phase compared to the first few of the next

Answer

Level change between phases is evaluated by comparing the terminal data points of one phase to the initial data points of the next phase.
