Statistical significance testing has dominated the way researchers typically report their results and evaluate their significance. This approach has been commonly used to determine the importance and generalizability of research results and to demonstrate the effect of an intervention in health research. However, this approach has limited use for clinicians and decision-makers trying to offer the best possible treatment to patients. Statistical significance does not assure that the results are clinically relevant. Indeed, the use of null hypothesis significance testing rarely determines the practical importance or clinical relevance of findings. Since public health specialists are interested in whether the intervention had an impact on clinical outcomes and also in the magnitude of such impact, relying solely on statistical significance to conclude about the relevance of results seems to be limited and insufficient (Armijo-Olivo, 2018).

Public health practice relies on the peer-reviewed public health literature for current research and findings that support an evidence basis for effective practice. Studies have shown that statistical literacy and knowledge are needed for understanding published research. The rapid growth and widespread availability of computing power and user-friendly statistical software packages in recent decades have led to the use of more advanced statistical methods and analyses being used and reported in the health literature. However, statistical training in public health may not have kept up with the modern data explosion and statistical complexities increasingly being applied in health studies and reported in scientific publications. A comprehensive understanding of statistical concepts and methods is essential for understanding current research and developing effective public health practice (Hayat et al., 2017).
