Question

Quizplus · Accepted Answer

Large differences between groups or variables in a study can be statistically significant, indicating a low probability that the observed differences occurred by chance. However, statistical significance does not always equate to practical significance. Practical significance refers to the real-world relevance or importance of the difference. A large difference might not be practically significant if it does not have a meaningful impact on the field of study, does not affect decision-making processes, or is not considered important by practitioners or stakeholders. Therefore, the statement that a large difference is always practically significant is not true, as practical significance depends on context, relevance, and application rather than just the size of the difference.
