Statistical Hypothesis Testing In Scientific Research: The Role Of Correlation Coefficients In Enhancing The Quality Of Media And Communication Studies



Authors : Benhmaida Amina .

Abstract

This study investigates the role of correlation coefficients in statistical hypothesis testing and their contribution to improving the quality of scientific research in media and communication studies. It focuses on the methodological conditions required for the correct application of Pearson and Spearman correlation coefficients, particularly in relation to data type, distribution, and measurement level. The research highlights common errors in selecting and interpreting correlation methods, which may affect the validity of scientific results. It also emphasizes the importance of choosing appropriate statistical tools to ensure accurate analysis of relationships between variables. The findings show that correct use of correlation analysis enhances the reliability and objectivity of research outcomes. In addition, the study underlines that correlation does not imply causation, requiring careful theoretical interpretation. Overall, the study contributes to improving methodological rigor in quantitative media research and strengthening the quality of academic publications.
