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.
Regression analysis is used to measure the degree of relationship between two or more RATIO variables. Consider any two RATIO variables, for example AGE and WAGES. One might reasonably expect that WAGES might increase as AGE increases, based on the hypothesis that one's experience increases with age.
