    • Statistical significance quantifies the probability of chance findings.
    • It does not equate to the importance or relevance of a finding.
    • Misinterpretation can arise from over-reliance on p-values.

    Conclusions:

    • Understanding the distinction between statistical and practical significance is crucial.
    • Researchers and readers should critically evaluate findings beyond mere statistical thresholds.
    • Contextual interpretation is key to avoiding misleading conclusions from statistical data.
