statistical significance

Statistical significance is a way to determine if the results of a study or experiment are likely due to chance or if they reflect a true effect. It helps researchers decide whether to accept or reject a hypothesis. A result is often considered statistically significant if the likelihood that it happened by chance is below a certain threshold, commonly set at 5% (0.05). In simpler terms, if a result is statistically significant, it suggests that there is strong evidence to support that the observed effect is real and not just random variation.
