![]() ![]() The stronger the correlation, the closer the correlation coefficient comes to ☑. The strength of relationship can be anywhere between −1 and 1. A correlation coefficient of zero indicates that no linear relationship exists between two continuous variables, and a correlation coefficient of −1 or 1 indicates a perfect linear relationship. It is a dimensionless quantity that takes a value in the range −1 to 1 3. 1 Correlation is measured by a statistic called the correlation coefficient, which represents the strength of the putative linear association between the variables in question. In statistical terms, correlation is a method of assessing a possible two-way linear association between two continuous variables. ![]() ![]() Webster's Online Dictionary defines correlation as a reciprocal relation between two or more things a statistic representing how closely two variables co-vary it can vary from −1 (perfect negative correlation) through 0 (no correlation) to 1 (perfect positive correlation). Misuse of correlation is so common that some statisticians have wished that the method had never been devised. This broad colloquial definition sometimes leads to misuse of the statistical term “correlation” among scientists in research. Among scientific colleagues, the term correlation is used to refer to an association, connection, or any form of relationship, link or correspondence. The term correlation is sometimes used loosely in verbal communication.
