What does it mean to say that the results of an experiment are "statistically significant"

Question

Quizplus · Accepted Answer

Statistically significant results mean that the differences observed between groups (experimental and control) or in measurements of the dependent variable were not due to chance. This is typically determined through statistical analysis and a pre-determined level of significance, such as p < 0.05. Practical significance (A) refers to the real-world importance of the results, which may or may not align with statistical significance. Choice B is the opposite of statistically significant, and choice D refers to the importance of publishing results, which is not directly related to statistical significance.
