Partial-interval recording tends to _______ the true occurrence of a behavior.
Answer: Overestimate
Because the behavior only needs to occur once during the interval to be scored, partial-interval recording often overestimates behavior prevalence.
When a BCABA graphs cumulative records, an accelerating slope indicates:
Answer: Behavior is increasing in rate over time
On a cumulative graph, a steeper slope reflects a higher rate of responding because each response adds to the running total.
Which reliability measure examines agreement only for intervals in which neither observer recorded the behavior?
Answer: Unscored-interval IOA
Unscored-interval IOA considers only intervals where both observers did not score the behavior, making it sensitive for high-rate behaviors.
A scatter plot in ABA is used primarily to identify:
Answer: Temporal patterns of behavior
Scatter plots display when during the day or across activities a behavior tends to occur, revealing temporal or contextual patterns.
The minimum generally accepted IOA percentage for published ABA research is:
Answer: 80%
An IOA of 80% or above is the widely accepted minimum threshold to demonstrate adequate measurement reliability in ABA research.
Which measurement dimension is most appropriate for assessing on-task behavior that occurs continuously?
Answer: Duration
Duration recording is ideal for continuous behaviors such as on-task behavior because it captures how long the behavior persists.
