Correlation Analysis. Correlation analysis is a method for measuring the covariance of two random variables in a matched data set. Covariance is usually expressed as the correlation coefficient of two variables X and Y. The correlation coefficient is a unitless number that varies from -1 to +1.
Correlation measures the closeness (link) of the relationship between two or many variables without knowing the functional relationships. In contrast, regression can show the form of the relationship of one independent variable with one dependent variable. The forms of the intrinsic linear relationship such as polynomial, exponential and logarithmic regression tend to have low correlation.
