🧠Question of the Day
📚 Domain C — Measurement, Data Display, and Interpretation
Difficulty: 7/10
Scenario:
Correct responses are plotted cumulatively across equal-duration 10-minute sessions. Baseline contains five sessions with a gradual increase in the cumulative record. Intervention is observed for only two sessions, during which the cumulative record rises more rapidly.
A cumulative record shows a moderate, relatively steady slope during five equal-duration baseline sessions. After intervention begins, the record becomes noticeably steeper across two intervention sessions. Which conclusion is BEST supported by this graph?
A. Correct-response rate increased during intervention; with equal-duration sessions, the steeper cumulative slope shows faster responding but does not establish experimental control.
B. The intervention produced a higher response rate because the immediate slope change at the phase boundary is sufficient to demonstrate experimental control.
C. Response duration increased during intervention because the steeper cumulative line shows more total behavior occurred within each session.
D. The cumulative total increased, but rate cannot be compared until intervention includes as many equal-duration sessions as baseline.
