ABA Data-Driven Decision Making 3

Question 1

A BCBA reviews a graph showing high variability in a client's data during the intervention phase. Which action should be taken FIRST before concluding the intervention is ineffective?

Accepted Answer

Investigate potential sources of variability

Answer

High variability should prompt investigation of environmental, procedural, or measurement factors before drawing conclusions about intervention effectiveness.

Question 2

In applied behavior analysis, what is an 'aim line' on a graph used to represent?

Accepted Answer

The projected path needed to meet the terminal goal by a target date

Answer

An aim line connects current performance to the terminal criterion at the target date, providing a benchmark against which actual data can be compared.

Question 3

Which level of measurement produces data that can be ordered and has equal intervals but no true zero point?

Accepted Answer

Interval

Answer

Interval scales have rank order and equal intervals between values, but lack a true zero, unlike ratio scales used for most behavioral counts.

Question 4

A behavior analyst is monitoring a decreasing behavior and the data path shows a decelerating trend. How should this be interpreted?

Accepted Answer

The behavior is decreasing at a consistent rate, suggesting the intervention is working

Answer

A decelerating trend in a target behavior intended for reduction indicates the intervention is producing the desired effect.

Question 5

When a practitioner uses IOA (interobserver agreement) data, what is the primary purpose in data-driven decision making?

Accepted Answer

To confirm that the data accurately reflect the behavior being measured

Answer

IOA data verifies measurement accuracy and reliability, which is essential before using data to make intervention decisions.
