Which statement best describes the reliability of the study conducted by Andrade?

• A. High reliability, due to diverse participants
• B. Somewhat low reliability, study was poorly designed
• C. Somewhat high reliability, likely to have similar results if replicated
• D. High reliability, with a consistent experimental procedure

Answer: (C)

The statement that the study conducted by Andrade has somewhat high reliability is accurate, especially in terms of its likelihood to yield similar results if replicated. High reliability in research refers to the consistency of the results when the study is repeated. Andrade’s methodology allowed for a level of control and standardization, which contributes to this reliability. The findings suggest a pattern that is likely to emerge again in similar contexts, indicating that the effects observed in the study are not random or isolated incidents.

Furthermore, the consideration for measuring doodling's effects on attention and memory indicates that Andrade crafted her study with careful thought to the variables involved, which supports replicability. While there might be some limitations to the sample size or diversity, the core aspects of the experimental procedure—such as the manner in which doodling was engaged and the subsequent assessments of memory retention—suggest a foundation that other researchers could follow to achieve similar outcomes. Thus, it provides a reasonable expectation for consistency in findings across repetitions of the experiment.
