This study concerned with comparing correlation coefficient (correlation) to copula functions (copulas) throughout their correlations, which are defined by means of their copulas . Indeed, it is an attempt to answer the following question, why copula functions (copula) is preferred in modern statistical inference to correlation?. We will discuss each topic individually, to make a right decision about the question above. For making our decision clear we have recalled some of the basic concepts related to correlation and copulas so that we can show the characteristics and differences of using each one.
