Question 1

Interobserver agreement (IOA) is calculated in ABA primarily to:

Accepted Answer

Assess the reliability and consistency of data collection between two independent observers

Answer

IOA measures how consistently two observers independently record the same behavior during the same session. High IOA indicates the data collection method and definitions are clear and reliable, which is essential for making valid clinical decisions.

Question 2

In ABC data collection, the 'C' component refers to:

Accepted Answer

Consequence

Answer

ABC stands for Antecedent, Behavior, Consequence. Recording the consequence captures what happens immediately after the behavior occurs, which helps identify the function maintaining that behavior.

Question 3

Which discontinuous measurement method records a behavior as having occurred if it is observed at any point during an interval, regardless of how long it lasts?

Accepted Answer

Partial interval recording

Answer

Partial interval recording marks an interval as 'yes' if the target behavior occurs at any moment within that interval. Because even a brief occurrence counts, this method tends to overestimate the true frequency or duration of the behavior.

Question 4

An RBT calculates the rate of a behavior by:

Accepted Answer

Dividing the number of occurrences by the length of the observation period

Answer

Rate = number of occurrences ÷ time (e.g., responses per minute). Unlike raw frequency, rate accounts for differences in session length, making comparisons across sessions more meaningful.

Question 5

On a standard ABA line graph, what does the x-axis (horizontal axis) represent?

Accepted Answer

Sessions or time

Answer

In ABA graphs, the x-axis represents sessions or time, showing how data unfolds across the course of treatment. The y-axis represents the behavioral measure (e.g., frequency, rate, or percentage).
