Which data collection method records whether a target behavior occurred at least once during a specific time interval?

Answer: Partial-interval recording

Partial-interval recording scores an interval as positive if the behavior occurs at any point during that interval.

A behavior analyst wants to measure the length of time between the presentation of an instruction and the learner's response. Which measurement dimension is being captured?

Answer: Latency

Latency measures the elapsed time from the onset of an antecedent stimulus to the initiation of the response.

Which of the following best describes inter-observer agreement (IOA)?

Answer: The degree to which two independent observers record the same data

IOA assesses the reliability of measurement by comparing data from two independent observers recording simultaneously.

Momentary time sampling records behavior:

Answer: Only at the moment the interval ends

Momentary time sampling records whether the behavior is occurring exactly at the moment the interval ends (the sample point).

A graph that displays cumulative responses over time, with slope indicating response rate, is called a:

Answer: Cumulative record

A cumulative record plots total responses over time; a steeper slope indicates a higher rate of responding.

Which measurement approach would be MOST appropriate for tracking aggression that varies in intensity and duration?

Answer: Duration recording with severity rating

Duration recording combined with a severity rating captures both how long aggressive episodes last and their intensity.

In ABA, a 'trial' most commonly refers to:

Answer: A single instance of the antecedent–behavior–consequence sequence

A trial is a discrete antecedent–behavior–consequence (A-B-C) sequence used as the basic unit of instruction in ABA.
