Which of the following is a factor not to consider when determining whether or not a functional relation has been demonstrated in an experiment?

• A. Variability of data
• B. Systematic replication of effects
• C. Time-series analysis
• D. Consistency of results across measures

Answer: (B)

A functional relation in an experiment indicates a consistent connection between changes in an independent variable and resulting changes in a dependent variable. When evaluating whether such a relationship has been demonstrated, various factors are crucial. The variability of data plays a significant role because high variability may obscure the effects of the treatment, making it difficult to determine a clear functional relationship. Time-series analysis is also important, as it provides a means to look at changes over time and helps establish trends that may indicate a functional relationship. Additionally, the consistency of results across measures can establish reliability and support the existence of a functional relationship. Systematic replication of effects, while valuable for strengthening conclusions in broader contexts or different settings, is not essential for establishing a functional relation within the confines of a single experiment. It primarily serves to confirm findings rather than being a prerequisite for demonstrating that a consistent effect occurs under specific experimental conditions. Therefore, it is appropriate not to consider this factor as critical in determining the establishment of a functional relationship in an initial experiment context.
