Final answer:
The reference material does not directly answer the given multiple-choice question but emphasizes the importance of sufficient sample size for reliable ABA research conclusions.
Step-by-step explanation:
For research in the field of Applied Behavior Analysis (ABA), it is recommended to design measurement systems that produce percentages based on sufficient data to enable reliable conclusions. The question specifies a quantity of response opportunities or observational units, suggesting that a minimum threshold is required for accurate data analysis. Based on the given reference information, none of the provided options are directly confirmed; the focus instead is on the importance of adequate sample size for statistical accuracy and the variability inherent in constrained samples. Although the reference material does not provide a direct answer, it highlights the necessity of avoiding conclusions from too few data points and the benefits of capturing a comprehensive sample when possible.
