RBT Competency #3 - Data/Graphs/Observable & Measurable Termss

What is a graph used for in ABA?

It is a visual representation of data collected, and helps to analyze trends/patterns in clients behavior or skill development.

What is the most common graph used in ABA?

The line graph

What is accuracy?

Whether the reported data represented what has actually occurred; aka observed/true value

What is reliability?

When the measurement gives the same results/data when presented repeatedly w/ the same events.

What is validity?

Whether what is being measured is actually a product of the behavior of interest during the observation.

What is the x axis and y axis?

The x axis is the horizontal line that represents the passage of time, usually labeled as date/session.

The y axis is the vertical line that identifies the type of measurement being collected usually labeled as frequency, duration, percent stc.

What is data?

Quantitative info collected on a clients behavior/skill acquisition; used to make informed decisions about the clients treatment plan.

Why is it important for BCBAs & RBTs to analyze the graph regularly?

To identify patterns & changes in client behavior

Who is responsible for analyzing AND INTERPRETING the data?

The BCBA

What are data points?

Individual measures of the target behavior plotted on the graph.

What is the data path?

Connecting data points on the graph in order to see trends & progress of behavior/skill

What are plot data points?

Represents a single measure of the target behavior/skill during a specific date/session.

How should an RBT describe the client’s behavior/environment in observable & measurable terms?

By using objective language & specific terms that avoids subjective interpretations or assumptions.

What are subjective interpretations?

Personal opinions, bias, or judgements that are based on individual perspectives/beliefs or emotions.

How should an RBT enter data & update graphs?

1st: Label the x axis(session/date) & y axis(measurement type).

2nd: Record the data collected.

3rd: Plot the data points.

4th: Connect the data points w/ a line to create the data path and visually see trends in behavior over time

5th: Analyze the graph to identify trends/patterns in behavior.

6th: Update the graph by adding new data points & extending data path

7th: Share the graph w/ Supervisor/BCBA or team & caregivers.
