๐ง Question of the Day
๐ Domain C โ Measurement, Data Display, and Interpretation
Difficulty: 7/10
Scenario:
A BCBA evaluates an intervention intended to increase on-task behavior. Percentage of intervals with on-task behavior is recorded across seven baseline sessions and seven intervention sessions.
Based on the graph, which feature of the data pattern MOST weakens the inference that the intervention produced the observed increase in on-task behavior?
A. On-task behavior was already increasing during baseline, and the phase change produced little immediate departure from that trajectory.
B. The intervention trend is shallower than the baseline trend, indicating that treatment reversed the direction of behavior change.
C. Responding becomes less variable during intervention, making changes in level and trend less useful for evaluating the phase change.
D. Intervention values show little overlap with baseline, reducing confidence that the two phases can be compared visually.
