Which of the following best describes practical significance?

The correct answer focuses on the importance of findings in real-world situations. Practical significance assesses whether the results of a study have meaningful implications outside of a statistical context. This is crucial in applied psychology, where the goal is often to determine not just if an effect exists, but whether that effect is substantial enough to be impactful in real-world applications.

For example, a study might find a statistically significant difference in test scores between two teaching methods. However, if the difference is minimal and does not translate to noticeable improvements in student performance, it may lack practical significance. Thus, practical significance allows researchers and practitioners to evaluate the relevance and applicability of their findings to everyday life, ensuring that their work can lead to meaningful changes or interventions.
