Statistical errors in health sciences research can greatly undermine the
dependability of study results, negatively impacting clinical decision-making and
policy development. This work focuses on the crucial task of minimizing
potential statistical errors that arise from inadequate sample size estimation and
improper analysis methodologies. The Sample Size & Statistical Analysis
Calculator (S2SAC) is a tool specifically developed to improve the precision and
dependability of statistical analyses in health research. S2SAC is a statistical
software that can be easily used within the Microsoft Excel environment. It has a
user-friendly interface and provides a wide range of statistical operations, such as
outlier detection, normality testing, and both parametric and non-parametric
tests. This application automates the intricate computations necessary for
accurate sample size estimation and reliable statistical analysis, allowing
researchers without substantial statistical experience to utilize advanced
statistical approaches easily. This paper examines the potential of S2SAC through
in-depth case studies, showcasing its efficacy in enhancing research design and
safeguarding the credibility of research outcomes in the field of health sciences.
