Question 1

A supervisor wants staff to measure the time from the onset of a demand to the start of problem behavior. Which measurement dimension is most appropriate?

Accepted Answer

Latency

Answer

Latency measures the elapsed time between the onset of a stimulus (such as a demand) and the initiation of the target response.

Question 2

Which graphing convention should a supervisor enforce to separate baseline and intervention phases on a line graph?

Accepted Answer

A vertical phase-change line

Answer

A vertical phase-change line is the standard convention used to demarcate transitions between experimental phases on behavioral graphs.

Question 3

A behavior analyst supervisor is reviewing cumulative records. A flattening of the cumulative record curve indicates what about the target behavior?

Accepted Answer

The behavior rate is decelerating or has stopped

Answer

On a cumulative graph, the slope represents rate; a flat or horizontal segment indicates zero or very low frequency of the behavior during that period.

Question 4

Which level of the measurement hierarchy involves calculating the proportion of total opportunities in which a behavior occurs?

Accepted Answer

Percentage

Answer

Percentage (or percent correct/occurrence) is calculated by dividing the number of occurrences by the total number of opportunities and multiplying by 100, normalizing for varying opportunity counts.

Question 5

A supervisor trains staff using the BACB's definition of IOA. What minimum IOA percentage is generally considered acceptable for published behavioral research?

Accepted Answer

80%

Answer

An IOA of 80% or above is the widely accepted minimum threshold in applied behavior analysis research to demonstrate adequate measurement reliability.
