Measurement and Data Collection Flashcards

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.
