Which type of IOA is most appropriate for low-rate behaviors?
Answer: Occurrence IOA
Occurrence IOA considers only intervals where at least one observer scored the behavior, making it more sensitive for infrequent behaviors.
A rate measure is calculated by dividing the number of responses by:
Answer: The session length
Rate (or frequency per unit time) is computed as the count of responses divided by the total observation time.
Whole-interval recording tends to _______ the true prevalence of a behavior.
Answer: Underestimate
Because whole-interval recording requires the behavior to occur throughout the entire interval to be scored, it typically produces an underestimate of behavior prevalence.
Which graphing format is most commonly used in applied behavior analysis to display data over time?
Answer: Simple line graph
Simple line graphs (equal-interval line graphs) are the standard in ABA because they clearly display behavioral trends across time.
A celeration chart (Standard Celeration Chart) measures behavior change on a:
Answer: Logarithmic frequency scale
The Standard Celeration Chart uses a semi-logarithmic scale, allowing equal visual representation of proportional change across orders of magnitude.
Which term describes the number of correct responses divided by the total number of opportunities, expressed as a percentage?
Answer: Percent correct
Percent correct is a ratio measure calculated by dividing correct responses by total opportunities and multiplying by 100.
