BCBA measurement practice questions for data and visual-analysis decisions
Measurement questions test more than definitions. They ask whether the data system, graph, reliability check, or interpretation supports the next behavior-analytic step.
Measurement review routine
- 1Name the target behavior and the measurement system before choosing an answer.
- 2Check whether the question is asking about data collection, reliability, graph interpretation, or decision making.
- 3Eliminate answers that change intervention before the data problem is resolved.
- 4After reviewing, write one sentence explaining what the data can and cannot support.
Measurement questions to review first
Review missed itemsOperational definitions: Measurement system selection.
Two observers collect data on repeating questions after instructions, but their session notes show different definitions and missed opportunities to score responses. Across 8 sessions in service week 3, 3 observers recorded 41 minutes of observation in the telehealth caregiver meeting. Before revising treatment, the BCBA should:
Review focus: Measurement system selection
Direct, indirect, and product measures: Measurement system selection.
A team reviews data on leaving the work area. The available record shows that escape follows the response on most trials, and task difficulty changed last week. The next program decision depends on whether the current data are trustworthy enough. Across 4 sessions in service week 4, one observer recorded 42 minutes of observation in the early intervention clinic. The BCBA should:
Review focus: Measurement system selection
Occurrence measurement: Measurement system selection.
Two observers collect data on calling out during independent work, but their session notes show different definitions and missed opportunities to score responses. Across 5 sessions in service week 4, 2 observers recorded 43 minutes of observation in the elementary classroom. Before revising treatment, the BCBA should:
Review focus: Measurement system selection
Temporal-dimension measurement: Measurement system selection.
A team reviews data on dropping to the floor after instructions. The available record shows that caregiver notes conflict with two direct observations. The next program decision depends on whether the current data are trustworthy enough. Across 6 sessions in service week 4, 3 observers recorded 44 minutes of observation in the home program. The BCBA should:
Review focus: Measurement system selection
Continuous versus discontinuous measurement: Measurement system selection.
Two observers collect data on pausing work after corrective feedback, but their session notes show different definitions and missed opportunities to score responses. Across 7 sessions in service week 4, one observer recorded 45 minutes of observation in the vocational training room. Before revising treatment, the BCBA should:
Review focus: Measurement system selection
Discontinuous measurement design and use: Measurement system selection.
A team reviews data on grabbing items from shelves. The available record shows that ABC notes show different consequences across stores. The next program decision depends on whether the current data are trustworthy enough. Across 8 sessions in service week 4, 2 observers recorded 46 minutes of observation in the community outing. The BCBA should:
Review focus: Measurement system selection
Efficiency measurement: Measurement system selection.
Two observers collect data on repeating questions after instructions, but their session notes show different definitions and missed opportunities to score responses. Across 4 sessions in service week 4, 3 observers recorded 47 minutes of observation in the telehealth caregiver meeting. Before revising treatment, the BCBA should:
Review focus: Measurement system selection
Measurement validity and reliability: Measurement quality and procedural integrity.
A team reviews data on leaving the work area. The available record shows that escape follows the response on most trials, and task difficulty changed last week. The next program decision depends on whether the current data are trustworthy enough. Across 5 sessions in service week 4, one observer recorded 48 minutes of observation in the early intervention clinic. The BCBA should:
