Random matrices have fascinated mathematicians and physicists since they were first introduced in mathe- matical statistics by Wishart in 1928. After a slow start‚ the subject gained prominence when Wigner introduced the concept of statistical distribution of nuclear energy levels in 1950. Since then‚ random matrix theory has matured into a field with applications in many branches of physics and mathematics‚ and nowadays random matrices find applications in fields as diverse as the Riemann

3.6.2 Correlation Analysis Correlation analysis is one of the data analysis method use in quantitative research when researchers intended to examine the relationship between both variables (Research Methodology‚ n.d.). The Pearson’s Moment Correlation Coefficient (PMCC) ranges between +1 and -1.If the coefficient value is +1 and -1‚ it is an indication that the relationships between both variables are strong. A value of +1 indicate that there is a positive relationship between variables‚ means that
