ABA Data-Driven Decision Making 2

Question 1

A BCBA notices a client's data path has been flat for 3 consecutive weeks despite an intervention. According to data-based decision rules, what is the most appropriate action?

Accepted Answer

Modify or change the intervention

Answer

Three consecutive data points showing no improvement (a flat trend) is a common decision rule indicating the intervention should be modified or changed.

Question 2

Which graphing convention is used in ABA to visually separate baseline and intervention phases?

Accepted Answer

A vertical phase change line

Answer

Vertical phase change lines are the standard ABA convention to separate and clearly distinguish different experimental phases on a graph.

Question 3

When calculating the mean of a data set for a phase, which measure is being computed?

Accepted Answer

The arithmetic average of all data points

Answer

The mean is the arithmetic average, calculated by summing all values and dividing by the number of data points.

Question 4

A practitioner plots data on a standard celeration chart. What does 'celeration' specifically measure?

Accepted Answer

The rate of change in frequency over time

Answer

Celeration is the rate of change (acceleration or deceleration) in response frequency across time, which is the primary metric of the Standard Celeration Chart.

Question 5

An ABA team is using a criterion-referenced decision rule. The goal is 80% accuracy for 3 consecutive sessions. The client scores 82%, 79%, 84%. Has the criterion been met?

Accepted Answer

No, because the second session fell below 80%

Answer

A consecutive sessions rule requires all specified sessions to meet criterion; one session below 80% breaks the consecutive requirement.
