More Information
Practical significance is subjective and context-dependent, meaning what is considered meaningful can vary depending on the situation and audience.
Tips
A common mistake is to confuse statistical significance with practical significance. While statistical significance indicates the likelihood that an observed effect is not due to chance, practical significance assesses the real-world importance of the effect.
