Original BCBA scenario practice question with answer explanation and wrong-choice notes.
Difficulty: hard. Skill: analyze. Type: data interpretation.
A BCBA needs to know how long each episode of screaming lasts in a early-intervention session. Which measurement system best fits this question? The team wants the next step to be defensible from the current data.
Correct answer
Duration recording measures how long behavior occurs, which matches the decision question in the stem.
Frequency counts occurrences but does not measure how long each episode lasts.
Latency measures time from an antecedent to response onset.
Permanent products measure outcomes left by behavior, not episode length here.
