In a correlational study the researcher measures variables as they naturally occur. They do not do anything to manipulate the variables. ... The Pearson Correlation Statistic ( r ) provides two separate pieces of information. (1) The sign, negative or positive tells us the direction of the relationship. If a correlation is positive, it ...

The population symbol for the Pearson Product Moment Correlation Coefficient. is rho [(]. The sample symbol for this correlation coefficient is r. The Pearson r can take on values ranging from -1.0 to +1.0. The direction of the relationship is indicated by the sign, positive or negative, associated with the Pearson r.

Since Pearson's correlation coefficient is a more appropriate measure than Spearman’s rank correlation when summing random variables in risk modeling (see Reference 2), we will concentrate on this correlation measure. By definition, Pearson's correlation coefficient (Pearson’s r) calculated between two sets of numbers {xi} and {yi} is given by:
