Board Certified Behavior Analyst (BCBA) — Question 32

What could be done to clarify the differentiation in the frequency of aggression among the environments shown in this graph?

Answer options

• A. Use an equal interval graph.
• B. Record data for an entire week.
• C. Include more environments along the horizontal axis.
• D. Change the vertical axis so that the range is zero to twenty.

Correct answer: D

Explanation

Changing the vertical axis to a range of zero to twenty will allow for a clearer view of the differences in aggression frequency across environments, making the data more interpretable. The other options do not directly address the issue of visualizing frequency differences, such as recording data for a week or including more environments, which may not enhance the clarity of the graph.
