Question 1

Which type of IOA is most appropriate for low-rate behaviors?

Accepted Answer

Occurrence IOA

Answer

Occurrence IOA considers only intervals where at least one observer scored the behavior, making it more sensitive for infrequent behaviors.

Question 2

A rate measure is calculated by dividing the number of responses by:

Accepted Answer

The session length

Answer

Rate (or frequency per unit time) is computed as the count of responses divided by the total observation time.

Question 3

Whole-interval recording tends to _______ the true prevalence of a behavior.

Accepted Answer

Underestimate

Answer

Because whole-interval recording requires the behavior to occur throughout the entire interval to be scored, it typically produces an underestimate of behavior prevalence.

Question 4

Which graphing format is most commonly used in applied behavior analysis to display data over time?

Accepted Answer

Simple line graph

Answer

Simple line graphs (equal-interval line graphs) are the standard in ABA because they clearly display behavioral trends across time.

Question 5

A celeration chart (Standard Celeration Chart) measures behavior change on a:

Accepted Answer

Logarithmic frequency scale

Answer

The Standard Celeration Chart uses a semi-logarithmic scale, allowing equal visual representation of proportional change across orders of magnitude.
